Guided Notes

Reflex angles are angles that measure more than _______° but less than _______°

Steps to draw a reflex angle:1. Subtract the reflex angle from 360º. 2. Draw the resulting angle as described above.3. Mark the required angle which is outside the one that has been drawn.

Your Angle Equations:Your Angle + Reflex Angle = 360° so,360° - Your Angle = Reflex Angle

Reflex Angle

78°

Together they equal _________° which is a full ________.

Rotation Guided Notes

VocabularyFull Circle is 360°Half Circle 180° (straight angle)¼ of a Circle is 90° (right angle)Rotation- the movement around

a centerClockwise- the forward

movement in the direction of a the hands on a clock

Counterclockwise- the opposite direction to the way which the hands on the clock move

You need to understand clearly what the terms such as turn, half turn, quarter turn, etc. mean in terms of angles. There are 360° in one complete turn, so the following are true:
