Front

In a right-angled triangle, which side is opposite to angle θ?

Back

The side opposite to angle θ is called the Opposite side.

Front

What is the tangent ratio in terms of the sides of a right triangle?

Back

Front

In relation to angle θ, what is the side adjacent to angle θ called?

Back

The side adjacent to angle θ is called the Adjacent side.

Front

Which side of a right triangle is always the longest?

Back

The hypotenuse is always the longest side of a right triangle.

Front

What does SOH stand for in trigonometry?

Back

SOH stands for Sine = Opposite / Hypotenuse.

Front

What does CAH stand for in trigonometry?

Back

CAH stands for Cosine = Adjacent / Hypotenuse.

Front

What does TOA stand for in trigonometry?

Back

TOA stands for Tangent = Opposite / Adjacent.

Front

If the opposite side is 3 and the adjacent side is 4, what is the tangent of the angle?

Back

Front

In a right triangle, if the hypotenuse is 5 and one side is 3, what is the length of the other side?

Back

Using the Pythagorean theorem, the other side is 4.
