Geometry Final Exam Review

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³).

Front

How do you calculate the density of an object?

Back

Density = Mass / Volume. For example, if a pebble has a mass of 17g and displaces 8mL of water, its density is 17g / 8mL = 2.125 g/mL.

What is the formula for the volume of a cone?

Back

Volume = (1/3)πr²h, where r is the radius of the base and h is the height of the cone.

Front

What is the measure of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is the measure of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

How do you find the probability of an event?

Back

Probability = (Number of favorable outcomes) / (Total number of possible outcomes).

Front

What is a similar polygon?

Back

Similar polygons are polygons that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What is the formula for the area of a triangle?

Back

Area = (1/2) × base × height.

Front

What is the Pythagorean theorem?

Back

In a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): a² + b² = c².

Front

What is the relationship between the angles in a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.
