Problem 1 Measuring Angles in Standard Position
What are the measures of each angle?
-
This angle is a counterclockwise rotation that makes a right angle so its measure is 90°.
Think
How many degrees are in a circle?
There are 360° in a circle, 180° in half of a circle, and 90° in a quarter of a circle.
-
This angle is a clockwise rotation that goes 45° beyond a right angle, so its measure is

What is the measure of the angle shown?
Problem 2 Sketching Angles in Standard Position
What is a sketch of each angle in standard position?
-
Think
What is the initial side of the angle?
In standard position, the initial side is always the positive x-axis.
-
315°

Two angles in standard position are coterminal angles if they have the same terminal side.
Angles in standard position, that have measures 135° and
