Module 5: Congruent Triangles

Front

What are Remote Interior Angles?

Back

Remote interior angles are the two angles inside a triangle that are not adjacent to a given exterior angle.

Front

What does the congruency statement ΔABC ≅ ΔEDC indicate?

Back

It indicates that triangle ABC is congruent to triangle EDC, meaning they have the same size and shape.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a theorem stating that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What additional information is needed to prove triangles are congruent using SSS?

Back

Front

What does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a theorem used to prove the congruence of right triangles.

Front

What is the definition of Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in the same position at each intersection where a straight line crosses two others.

Front

What is the definition of Interior Angles?

Back

Interior angles are the angles formed inside a polygon.

Front

What is the definition of Exterior Angles?

Back

Exterior angles are the angles formed outside a polygon when one side is extended.

Front

What is the AAS theorem in triangle congruence?

Back

AAS stands for Angle-Angle-Side, which states that if two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, the triangles are congruent.

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.
