Finding Trig Ratios

Front

What is the hypotenuse in a right triangle?

Back

The hypotenuse is the side opposite the right angle and is the longest side of the triangle.

Front

How do you identify the hypotenuse in a triangle labeled with sides a, b, and c?

Back

In a right triangle, the hypotenuse is always side c.

Front

From angle C in a right triangle, which side is AB?

Back

AB is the opposite side from angle C.

Front

What mnemonic helps remember the trigonometric ratios?

Back

Soh Cah Toa.

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.
