Topic Test Review 5 & 6 Review Part 1

Front

What is the definition of congruent triangles?

Back

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

Front

What theorem states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent?

Back

SAS (Side-Angle-Side) Theorem.

Front

What is the SSS Congruence Theorem?

Back

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

Front

What are Alternate Interior Angles?

Back

Angles that are on opposite sides of a transversal and inside the two lines it intersects.

Front

What is the value of x if triangles ABC and DEF are congruent and AB = 4, BC = x, and DE = 4, EF = 6?

Back

x = 6.

Front

What is the definition of Vertical Angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

What is the Angle Bisector Theorem?

Back

It states that the angle bisector of an angle in a triangle divides the opposite side into two segments that are proportional to the other two sides.

Front

Back

Their corresponding angles are equal, and their corresponding sides are proportional.

Front

What is the definition of Alternate Exterior Angles?

Back

Angles that are on opposite sides of a transversal and outside the two lines it intersects.

Front

Back

y = 8.
