Module 05 Test

Front

What is the definition of congruent triangles?

Back

Triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence where two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.

Front

What is the Angle-Side-Angle (ASA) criterion for triangle congruence?

Back

ASA states that if two angles and the side between them in one triangle are equal to two angles and the side between them in another triangle, then the triangles are congruent.

Front

Define the term 'midpoint' in geometry.

Back

A midpoint is a point that divides a line segment into two equal parts.

Front

What is the relationship between the angles in an equilateral triangle?

Back

In an equilateral triangle, all three angles are equal and each measures 60 degrees.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a criterion for triangle congruence where two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle.

Front

What is the definition of corresponding angles in congruent triangles?

Back

Corresponding angles are angles that are in the same relative position in two different triangles that are congruent.

Front

What is the significance of the HL theorem in triangle congruence?

Back

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

Front

How do you find the measure of an angle in a triangle if you know the other two angles?

Back

To find the measure of an unknown angle in a triangle, subtract the sum of the known angles from 180 degrees.

Front

What is the definition of an equilateral triangle?

Back

An equilateral triangle is a triangle in which all three sides are of equal length and all three angles are equal.
