Geo Final Review

Front

If m∠1 = 30°, what is m∠3?

Back

m∠3 = 30° (Vertical angles are equal).

Front

What is the probability of NOT rolling a 3 on a single die?

Back

5/6 (There are 5 outcomes that are not 3).

Front

Given two parallel lines cut by a transversal, what is the vertical angle to angle 4?

Back

Angle 7 (Vertical angles are equal).

Front

If Angle 1 = 3x - 4 and Angle 3 = 5x - 38, find the measure of Angle 4.

Back

Angle 4 = 133° (Solve for x and substitute).

Front

What is the probability that a randomly picked student is female if the probability is .5694?

Back

.5694 (This is the given probability).

Front

Define vertical angles.

Back

Vertical angles are the angles opposite each other when two lines cross. They are always equal.

Front

What is the sum of the interior angles of a triangle?

Back

180° (The sum of the angles in any triangle is always 180°).

Front

What is the formula for calculating probability?

Back

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

Front

What are complementary angles?

Back

Complementary angles are two angles whose sum is 90°.

Front

What is the definition of parallel lines?

Back

Parallel lines are lines in a plane that never meet and are always the same distance apart.
