Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What is a congruency statement?

Back

A congruency statement is a mathematical statement that shows two geometric figures are congruent, often written as ∆ABC ≅ ∆DEF.

Front

What is the symbol for congruence?

Back

The symbol for congruence is '≅'.

Front

If ∆EHG≅∆KFC, what can we say about their corresponding sides?

Back

The corresponding sides of the triangles are equal in length.

Front

What is the value of y if y + 2 = 10?

Back

y = 8.

Front

Solve for x: 2x + 3 = 13.

Back

x = 5.

Front

What is the measure of a right angle?

Back

A right angle measures 90 degrees.

Front

What is the sum of the angles in a triangle?

Back

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

Front

If one angle measures 60 degrees, what is the measure of the other two angles in an equilateral triangle?

Back

Each of the other two angles also measures 60 degrees.

Front

What does it mean if two angles are complementary?

Back

Two angles are complementary if the sum of their measures is 90 degrees.
