What is the Hypotenuse-Leg (HL) Congruence Theorem?

Back

The Hypotenuse-Leg (HL) Congruence Theorem states that if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the two triangles are congruent.

Front

What does it mean for triangles to be congruent?

Back

Triangles are congruent if they have the same size and shape, which means their corresponding sides and angles are equal.

Front

What is the definition of Alternate Exterior Angles?

Back

Alternate Exterior Angles are pairs of angles that lie outside two parallel lines and on opposite sides of a transversal.

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 Side-Side-Side (SSS) Congruence Postulate?

Back

The Side-Side-Side (SSS) Congruence Postulate states that if three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.

Front

What is the Side-Angle-Side (SAS) Congruence Postulate?

Back

The Side-Angle-Side (SAS) Congruence Postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.

Front

What is the Angle-Angle-Side (AAS) Congruence Theorem?

Back

The Angle-Angle-Side (AAS) Congruence Theorem states that if two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the triangles are congruent.

Front

What is the Corresponding Angles Postulate?

Back

The Corresponding Angles Postulate states that if two parallel lines are cut by a transversal, then each pair of corresponding angles is congruent.

Front

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

Back

To find the measure of an unknown angle in a triangle, use the fact that the sum of the interior angles in a triangle is always 180 degrees.

Front

What is the definition of Corresponding Angles?

Back

Corresponding Angles are pairs of angles that are in the same position on two parallel lines in relation to a transversal.
