Exploring Trigonometric Ratios

What does the hypotenuse of a right triangle represent?

• The longest side of the triangle

• The shortest side of the triangle

• The side adjacent to the right angle

• The side opposite to the right angle

What does the adjacent side of an angle in a right triangle represent?

• The side forming the right angle

• The side opposite to the angle

• The longest side of the triangle

• The side forming the angle with the hypotenuse

How is the sine of an angle in a right triangle defined?

• Opposite over Hypotenuse

• Opposite over Adjacent

• Hypotenuse over Opposite

• Adjacent over Hypotenuse
