GEO H 6/7 Test

Front

Identify the pair of angles that are on opposite sides of a transversal and outside the two lines.

Back

Alternate exterior angles.

Front

What is the name of a polygon with 5 sides?

Back

Pentagon.

Front

What congruency postulate can be used to prove that two triangles are congruent if two sides and the included angle are known?

Back

SAS (Side-Angle-Side).

Front

If Q is the midpoint of PR and PQ = 6x - 7, QR = 5x + 1, how do you find the length of PR?

Back

Set PQ = QR, solve for x, then calculate PR.

Front

What is the measure of angle DBC if BD bisects angle ABC and m∠ABD = 5(x - 6) and m∠DBC = 2x + 9?

Back

35°.

Front

Define corresponding angles in relation to parallel lines and a transversal.

Back

Corresponding angles are on the same side of the transversal and in corresponding positions.

Front

What is the formula for finding the sum of the interior angles of a polygon?

Back

(n - 2) × 180°, where n is the number of sides.

Front

What is the definition of a bisector in geometry?

Back

A bisector is a line that divides an angle or a segment into two equal parts.

Front

What does the acronym ASA stand for in triangle congruence?

Back

Angle-Side-Angle.

Front

What is the relationship between alternate interior angles when two parallel lines are cut by a transversal?

Back

Alternate interior angles are equal.
