Geometry Chapter 4 Review

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 does SAS stand for in triangle congruence?

Back

Side-Angle-Side; a postulate that states 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.

Front

What is the definition of vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always congruent.

Front

What is the Alternate Interior Angles Theorem?

Back

If two parallel lines are cut by a transversal, then each pair of alternate interior angles is congruent.

Front

What is the SSS postulate?

Back

Side-Side-Side; a postulate that states if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the ASA postulate?

Back

Angle-Side-Angle; a postulate that states if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

How do you find the measure of an angle in a triangle?

Back

The sum of the interior angles in 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; they are congruent.

Front

What is the definition of a transversal?

Back

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

Front

What is the relationship between alternate exterior angles when two lines are parallel?

Back

Alternate exterior angles are congruent when two parallel lines are cut by a transversal.
