C.1- C.6 Test

Front

What is the value of c in a triangle if the angles are 73.3, 90, and c?

Back

c = 180 - (73.3 + 90) = 16.7

Front

Define supplementary angles.

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

Which angles are supplementary to each other: <6 and <8, <7 and <11, <9 and <10, <9 and <6?

Back

<9 and <10 are supplementary.

Front

What is the measure of angle FG if it is given as 76 degrees?

Back

FG = 76 degrees.

Front

What does it mean if a point V lies in the exterior of an angle?

Back

It means that point V is outside the angle formed by the two rays.

Front

What is the value of RU if it is given as 87?

Back

RU = 87.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

If two angles are complementary, what is their sum?

Back

The sum of two complementary angles is 90 degrees.

Front

What is the definition of an exterior angle in a triangle?

Back

An exterior angle is formed by one side of a triangle and the extension of an adjacent side.

Front

How do you find the measure of an unknown angle in a triangle?

Back

Subtract the sum of the known angles from 180 degrees.
