Finding the Missing Angle
1) In the figure, ABCD is a rectangle and ∠CAD = 31∘. Find ∠BAC.
X= _____________
X
2) Describe how you could find <BAC without using a protractor.
The Helicopter
3)
The blades on a propeller turn and then pause. After 25 seconds the propeller blades
begin moving again and rotate another 80 degrees to complete a full 360 degrees. How
many degrees did the blades turn before they paused?
_______________ Degrees
The Ceiling Fan
4) A ceiling fan has five blades which are evenly spaced on the fan. If the first blade and the
second blade form an angle that is 72°, what would be the measure of the angle formed by the
first and third fan blade?
_______________ Degrees
