Review congruent angles & sides

Front

What does the Triangle Sum Theorem state about the angles in a triangle?

Back

The sum of all angles in a triangle is 180°.

Front

If two triangles are congruent, what can be said about their corresponding sides?

Back

The corresponding sides of congruent triangles are equal in length.

Front

If ∆LMK ≅ ∆LMT, what can be concluded about the angles K and T?

Back

∠K ≅ ∠T.

Front

What is the minimum requirement for three lengths to form a triangle?

Back

The sum of the lengths of any two sides must be greater than the length of the third side.

Front

What is the measure of each angle in an equilateral triangle?

Back

Each angle in an equilateral triangle measures 60°.

Front

What is the definition of congruent triangles?

Back

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

Front

What is the relationship between vertical angles?

Back

Vertical angles are equal to each other.

Front

How can you determine if two triangles are congruent using side lengths?

Back

If all three sides of one triangle are equal to the three sides of another triangle, the triangles are congruent (Side-Side-Side postulate).

Front

What is the Angle-Angle (AA) criterion for triangle similarity?

Back

If two angles of one triangle are equal to two angles of another triangle, the triangles are similar.

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.
