What is the sum of the interior angles of a triangle?
270°
360°
180°

In any triangle, the sum of the interior angles is 180°. This is a fundamental property used in many geometry problems.
What is the measure of a right angle?
45°
90°
180°
120°
A right angle is defined as having a measure of 90°. This is one of the basic angle measures in geometry.
How many sides does a pentagon have?
5
4
7
6
A pentagon is a five-sided polygon. Recognizing shapes and their properties is a key aspect of geometry.
Which term describes two lines that never intersect?
Parallel
Skew
Intersecting
Perpendicular
Parallel lines are defined as lines in the same plane that do not meet, regardless of how far they are extended. This makes them distinct from intersecting or skew lines.
What is the measure of each interior angle in a square?
90°
45°
180°
120°
A square is a regular quadrilateral with four equal angles. Each interior angle in a square measures 90°.
When a transversal intersects parallel lines, which pair of angles is NOT congruent?
Alternate exterior angles
Corresponding angles
Consecutive interior angles
Alternate interior angles
When a transversal cuts parallel lines, alternate interior, alternate exterior, and corresponding angles are congruent. However, consecutive interior angles are supplementary, not congruent.
What is the formula for the area of a circle?
r²
2πr
πd
πr²
The area of a circle is calculated using the formula A = πr², where r represents the radius. This formula is a cornerstone in problems involving circles.
What is the slope of a line perpendicular to a line with slope m (m 0)?
-m
-1/m
1/m
m
The slope of a line perpendicular to another is the negative reciprocal of the original line's slope. This relationship is fundamental in coordinate geometry problems.
Which of the following properties is true for all parallelograms?
Opposite sides are parallel
Only one pair of sides is parallel
Diagonals are congruent
All angles are 90°
A parallelogram is defined by having both pairs of opposite sides parallel. The other properties mentioned do not hold for every parallelogram.
In a triangle, if one angle measures 50° and another 60°, what is the measure of the third angle?
80°
70°
90°
100°
The sum of the interior angles in a triangle is always 180°. Subtracting the two given angles (50° and 60°) from 180° leaves 70° for the third angle.
If two similar triangles have corresponding side lengths in the ratio 2:3, what is the ratio of their areas?
9:4
4:9
3:2
2:3
The areas of similar figures scale by the square of the ratio of corresponding sides. Squaring the side ratio 2:3 gives the area ratio 4:9.
What is the distance between the points (2, -3) and (7, 1) in the coordinate plane?
7
9
√41
√29
Using the distance formula √[(7-2)² + (1-(-3))²], we calculate the distance as √(5² + 4²) = √(25+16) = √41. This method is essential for solving coordinate geometry problems.
An isosceles triangle has two sides of equal length. If the base measures 10 units and each leg measures 13 units, what is the triangle's perimeter?
36 units
30 units
40 units
26 units
The perimeter is found by adding all the side lengths. Here, 10 + 13 + 13 equals 36 units.
Which transformation reflects a point over the y-axis in the coordinate plane?
(x, y) becomes (-x, y)
(x, y) becomes (-x, -y)
(x, y) becomes (y, x)
(x, y) becomes (x, -y)
Reflecting a point over the y-axis changes the sign of the x-coordinate while leaving the y-coordinate unchanged. This transformation is commonly used in coordinate geometry.
If two lines are perpendicular in the coordinate plane (with non-vertical lines), what is the product of their slopes?
0
-1
Undefined
1
Perpendicular lines have slopes that are negative reciprocals of each other. Multiplying these slopes yields a product of -1.
Given a circle with a radius of 6 units, what is its circumference in terms of π?
12π
18π
6π
36π
The circumference of a circle is calculated as 2πr. With a radius of 6 units, the calculation is 2π(6) = 12π.
A circle is inscribed in a square with an area of 64 square units. What is the area of the inscribed circle in terms of π?
32π
8π
64π
16π
A square with an area of 64 has a side length of 8. The inscribed circle has a diameter equal to 8, giving it a radius of 4. Its area is then π(4²) = 16π.
Which set of three consecutive integers represents the side lengths of a right triangle?
4, 5, 6
5, 6, 7
3, 4, 5
6, 7, 8
The 3-4-5 triangle is the classic Pythagorean triple and is the only set of three consecutive integers that forms a right triangle. This set satisfies the Pythagorean theorem.
What is the volume of a right circular cone with a radius of 3 units and a height of 9 units, in terms of π?
81π
27π
18π
9π
The volume of a cone is given by V = (1/3)πr²h. Substituting r = 3 and h = 9 results in V = (1/3)π(9)(9) = 27π.
In a circle, a chord measures 10 units and the circle's radius is 7 units. What is the distance from the center of the circle to the chord?
4√2
√6
2√3
2√6
Using the chord length formula 10 = 2√(49 - d²), we solve for d²: 49 - d² = 25, so d² = 24 and d = √24, which can be simplified to 2√6. This is the perpendicular distance from the chord to the center.

Geometry Florida EOC Practice Test Cheat Sheet

  1. Master the Pythagorean Theorem - In any right triangle, the square of the hypotenuse (c) equals the sum of the squares of the other two sides (a² + b²). It's essential for finding missing lengths - think of 3‑4‑5 and 5‑12‑13 as your trusty number combos! Dummies.com
  2. Understand Special Right Triangles - In a 45°‑45°‑90° triangle, the legs match and the hypotenuse is √2 times a leg. In a 30°‑60°‑90° triangle, the hypotenuse doubles the shorter leg and the longer leg is √3 times it - no extra calculations needed! Dummies.com
  3. Calculate Areas of Polygons - Parallelogram area is base × height, trapezoid is ½ × (base₝ + base₂) × height, and regular polygons use ½ × perimeter × apothem. Mastering these formulas turns any shape into a quick math snack. Dummies.com
  4. Memorize Circle Formulas - Circumference is 2πr or πd, and area is πr². Plugging in r=3 gives area=9π - geometry magic at its finest! Dummies.com
  5. Apply the Slope Formula - The slope m = (y₂ - y₝) / (x₂ - x₝) measures a line's steepness and direction. Remember: parallel lines share slopes, and perpendicular ones have slopes that are negative reciprocals. Dummies.com
  6. Use the Distance Formula - Distance between (x₝,y₝) and (x₂,y₂) is √[(x₂ - x₝)² + (y₂ - y₝)²]. Between (1,2) and (4,6) it's √(3²+4²)=5 - a quick way to measure any gap on a plane. Dummies.com
  7. Understand Transformations - Translations slide figures, rotations turn them, reflections flip them, and dilations resize them. Visualizing these moves is like playing a geometry video game - get the sequence right and win every time! FLVS EOC Resources
  8. Learn Volume Formulas for 3D Shapes - For prisms & cylinders, volume = base area × height; pyramids & cones use ⅓×base area×height; spheres are 4/3πr³. These let you imagine filling shapes with water - perfect for any 3D problem! Dummies.com
  9. Review Properties of Quadrilaterals - Parallelograms have equal opposite sides, rectangles have right angles, squares combine both, rhombuses have all sides equal, and trapezoids mix parallel with nonparallel sides. Spot these traits to classify any four‑sided figure in a snap! FLVS EOC Resources
  10. Practice Proofs and Reasoning - Writing geometric proofs is like crafting a detective story: start with postulates, apply theorems, and connect the dots. Strong deductive reasoning and clear steps show you truly understand the shape of every argument. FLVS EOC Resources
