Triangles Test

Front

What is the Hypotenuse-Leg (HL) theorem?

Back

The Hypotenuse-Leg theorem states that if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the two triangles are congruent.

Front

What does the Angle-Side-Angle (ASA) postulate state?

Back

The Angle-Side-Angle postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

Front

What is the Angle-Angle-Side (AAS) theorem?

Back

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

Front

What is the Side-Angle-Side (SAS) postulate?

Back

The Side-Angle-Side postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

Front

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

Back

If the lengths of all three sides of one triangle are equal to the lengths of all three sides of another triangle, then the triangles are congruent.

Front

What is the significance of the longest side in a triangle?

Back

In a triangle, the longest side is opposite the largest angle, and the shortest side is opposite the smallest angle.

Front

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

Back

In a triangle, larger angles are opposite longer sides, and smaller angles are opposite shorter sides.

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

What is the definition of a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.
