Proving Triangles Congruent Practice

Front

What is a median in a triangle?

Back

A median is a line segment that connects a vertex of a triangle to the midpoint of the opposite side, cutting that side into two congruent segments.

Front

What does the Reflexive Property state?

Back

The Reflexive Property states that any geometric figure is congruent to itself.

Front

What is the significance of Vertical Angles in triangle congruence?

Back

Vertical Angles are always congruent, which can be used as a reason in proving triangles congruent.

Front

What is an altitude in a triangle?

Back

An altitude is a perpendicular segment from a vertex to the line containing the opposite side, creating two congruent right angles.

Front

What does CPCTC stand for?

Back

CPCTC stands for Corresponding Parts of Congruent Triangles are Congruent.

Front

How do you determine the smallest angle in a triangle?

Back

The smallest angle in a triangle is opposite the shortest side.

Front

What is the Definition of Midpoint?

Back

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

Front

What is the Definition of a Bisector?

Back

A bisector is a line or segment that divides another segment or angle into two equal parts.

Front

What are Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that are on opposite sides of a transversal and inside the two lines it intersects, and they are congruent when the lines are parallel.

Front

What is the purpose of using congruence postulates (SSS, SAS, ASA, AAS)?

Back

Congruence postulates are used to prove that two triangles are congruent based on specific criteria.
