Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a postulate used to prove that two triangles are congruent 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.

Front

What is the definition of vertical angles?

Back

Vertical angles are the angles opposite each other when two lines cross. They are always equal.

Front

What does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a theorem used to prove that two right triangles are congruent if the hypotenuse and one leg of one triangle are equal to the hypotenuse and one leg of another triangle.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others. They are equal when the lines are parallel.

Front

What is the SSS postulate in triangle congruence?

Back

SSS stands for 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 in triangle congruence?

Back

ASA stands for 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

What does SAS stand for in triangle congruence?

Back

SAS stands for 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 a transversal?

Back

A transversal is a line that intersects two or more lines at different points. It creates various angles, including corresponding angles, alternate interior angles, and alternate exterior angles.

Front

What is the definition of alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie on opposite sides of the transversal and inside the two lines. They are equal when the lines are parallel.

Front

What is the definition of alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie on opposite sides of the transversal and outside the two lines. They are equal when the lines are parallel.
