Geom Chapter 4 Review

Front

What is the definition of congruent triangles?

Back

Triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.

Front

What theorem can be used to prove two triangles are congruent if two sides and the included angle are known?

Back

SAS (Side-Angle-Side) Congruence Theorem.

Front

What theorem can be used to prove two triangles are congruent if all three sides are known?

Back

SSS (Side-Side-Side) Congruence Theorem.

Front

What theorem can be used to prove two right triangles are congruent if the hypotenuse and one leg are known?

Back

HL (Hypotenuse-Leg) Congruence Theorem.

Front

What is the Segment Addition Postulate?

Back

If point B is between points A and C, then AB + BC = AC.

Front

What is the Triangle Sum Property?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What is the definition of corresponding angles?

Back

Angles that are in the same position on different parallel lines cut by a transversal.

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 definition of a transversal?

Back

A line that intersects two or more lines at different points.

Front

What is the definition of angle addition?

Back

If point B is in the interior of angle AOC, then angle AOB + angle BOC = angle AOC.
