What does the ASA postulate state?

Back

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

What is the definition of congruent triangles?

Back

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

What is the HL theorem?

Back

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

What is the difference between acute, obtuse, and right triangles?

Back

An acute triangle has all angles less than 90 degrees, an obtuse triangle has one angle greater than 90 degrees, and a right triangle has one angle equal to 90 degrees.

How can you determine if two triangles are congruent using the SSS postulate?

Back

The SSS (Side-Side-Side) postulate states that if all three sides of one triangle are equal to the three sides of another triangle, then the two triangles are congruent.

What is the definition of an angle?

Back

An angle is formed by two rays (sides) that share a common endpoint (vertex).

Front

What is the relationship between the angles in a triangle?

Back

The relationship is that the sum of the angles in a triangle is always 180 degrees.
