What is the definition of a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

What is the Pythagorean theorem?

Back

In a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): a² + b² = c².

Front

What is the cosine function in trigonometry?

Back

The cosine function relates the angle of a right triangle to the ratio of the length of the adjacent side to the length of the hypotenuse.

Front

What is the sine function in trigonometry?

Back

The sine function relates the angle of a right triangle to the ratio of the length of the opposite side to the length of the hypotenuse.

Front

What is the tangent function in trigonometry?

Back

The tangent function relates the angle of a right triangle to the ratio of the length of the opposite side to the length of the adjacent side.

Front

What is an angle bisector?

Back

An angle bisector is a line or ray that divides an angle into two equal parts.

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.

Front

What is the Reflexive Property in geometry?

Back

The Reflexive Property states that any quantity is equal to itself, i.e., a = a.

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 equal.
