Hypotenuse, Opposite, and Adjacent

The hypotenuse of a right triangle is always the side opposite the right angle. It is the __________________ side in a right triangle.

• shortest

• longest

A right triangle has three sides: hypotenuse, opposite, and adjacent. The opposite side is across from a given angle. The __________________ side is the non-hypotenuse side that is next to a given angle.

• opposite

• adjacent

Which side length is adjacent to ∠A?

Which side is adjacent to ∠B?

• AB

• BC

• AC

Trigonometry is the measuring of triangles.

• true

• false

Real-life examples of trigonometry include

• a pilot's angle of descent

• height of a tree using the length of its shadow

• volume of water in swimming pool

We can use trigonometry to solve for unknown sides and angles in ___________________ triangles.
