Summative Test in Geometry (Unit 7)

Front

What is the angle of elevation?

Back

The angle of elevation is the angle formed by the horizontal line and the line of sight to an object above the horizontal line.

Front

How do you calculate the angle of elevation using a right triangle?

Back

Use the tangent function: tan(angle) = opposite/adjacent. Rearranged, angle = tan^(-1)(opposite/adjacent).

Front

What is the sine of an angle if the opposite side is 27 and the hypotenuse is 45?

Front

How do you find the missing angle in a triangle?

Back

Use the fact that the sum of angles in a triangle is 180 degrees. If two angles are known, subtract their sum from 180 to find the missing angle.
