Front

What is the measure of vertical angles?

Back

Vertical angles are equal in measure.

Front

What is the AAS postulate in triangle congruence?

Back

AAS (Angle-Angle-Side) states that if two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, then the triangles are congruent.

Front

How do you find the measure of an unknown angle in a triangle?

Back

Use the fact that the sum of the angles in a triangle is 180 degrees.

Front

What does it mean to translate a triangle?

Back

To translate a triangle means to move it to a different position without changing its shape or size.

Front

What type of triangle has all sides of equal length?

Back

An equilateral triangle.

Front

What is the definition of an isosceles triangle?

Back

An isosceles triangle has at least two sides of equal length.

Front

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

Back

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

Front

What is the definition of supplementary angles?

Back

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

Front

What is the definition of alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two lines.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.
