To determine the value of the cosine of an angle in a right triangle, divide the length of the side adjacent to the angle by the length of the hypotenuse. The hypotenuse of a right triangle is the side opposite to the ri... More » Math Geometry Trigonometry

The Hypotenuse Angle Theorem states that if one of the acute angles and the hypotenuse of a right triangle are congruent to the corresponding acute angle and hypotenuse of a second triangle, \this proves that the two tri... More »

The tangent-secant theorem states that if two secant segments share an endpoint outside of a circle, the product of one segment length and the length of its external segment equals the product of the other segment's leng... More » Math Geometry Trigonometry

Eighth grade students spend much time on Pythagorean Theorem problems, which require the formula a^2 + b^2 = c^2 to solve for the length of one side of a right triangle when given the lengths of the other two sides. If t... More » Education K-12
