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

Back

The 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.

What is the Reflexive Property of Congruence?

Back

The Reflexive Property states that any geometric figure is congruent to itself. For example, if triangle ABC is considered, then triangle ABC ≅ triangle ABC.

How do you find the midpoint of a line segment between two points A(x1, y1) and B(x2, y2)?

Back

The midpoint M is calculated using the formula: M = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What is the definition of an angle?

Back

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

Front

What is the sum of the interior angles of a triangle?

Back

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

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.
