Summative Test 1 (Trigonometric Ratios)

_____________ is the branch of Mathematics that deals with triangle measurement.

Trigonometry came from the Greek word "trigonon" which means ___________.

The Greek word "metron" means to _________.

_________ refers to the segment of a triangle that is always opposite the right angle.

• Leg

• Hypotenuse

• Altitude

• Median

The trigonometric functions are also called as _____________,

as the value of each function is written as the quotient of the lengths of the

two sides of a right triangle for a reference angle θ.

• trigonometric equation

• trigonometric inequality

• trigonometric ratio

• trigonometric proportion

What formula should be used to find the length of the third side?

• Distance Formula

• Midpoint Formula

• Pythagorean Formula

• Quadratic Formula

Which formula will help us find the value of x?
