Intro to Trig

Correctly place each vocab word with it's definition.

• Sides that are across from a given angle

• hypotenuse side

• right triangles

• opposite side

• Opposite of right angle & longest side

• Sides that are next to a given angle

• adjacent side

Correctly identify the opposite, the adjacent, and the hypotenuse side from angle B.

The side marked x is ​ (a)   to the angle that is 56 degrees. The side marked 20 is the ​ (b)   of the right triangle since it is across from the right angle. If we set up the ratio ​ x/20, we would be finding ​ (c)   56.
