Front

What is the congruency statement for angles in a triangle?

Back

If two angles in a triangle are congruent, then the third angle can be found by subtracting the sum of the two congruent angles from 180°.

Front

What does it mean for triangles to be similar?

Back

Triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

In an isosceles triangle, what is the relationship between the base angles and the vertex angle?

Back

The base angles are equal, and the vertex angle can be found by subtracting the sum of the base angles from 180°.

Front

If an isosceles triangle has a base angle measuring 40°, what is the measure of the vertex angle?

Back

100°.

Front

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

Back

The measure of an exterior angle is equal to the sum of the measures of the two non-adjacent interior angles.

Front

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

Back

180°.

Front

What is the definition of congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

What is the definition of an isosceles triangle?

Back

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

Front

What is the relationship between the sides and angles in a triangle?

Back

In a triangle, the larger angle is opposite the longer side, and the smaller angle is opposite the shorter side.

Front

How do you determine if two triangles are congruent?

Back

Two triangles are congruent if their corresponding sides and angles are equal.
