FAQs: Unit 8 Test Right Triangles And Trigonometry Answer Key

What is the Pythagorean theorem?

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

How do I find the sine of an angle?

The sine of an angle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.

What is the difference between sine and cosine?

Sine is the ratio of the length of the side opposite the angle to the length of the hypotenuse, while cosine is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse.
