## Vocabulary Report

• angle - formed by two rays or line segments that meet at the same endpoint
• right angle - an angle that forms a square corner and has a measure of 90°
• obtuse angle - an angle that has a measure greater than 90° and less than 180°
• degree (°) -  a unit for measuring angles and temperatures
• straight angle - an angle that forms a line and has a measure of 180°
• vertex -  the point at which two rays of an angle or two (or more) line segments meet in a two-dimensional shape
• reflex angle - an angle that has a measure greater than 180° and less than 360°
• clockwise - the direction the hands of a clock move
• protractor - a tool for measuring the size of an angle
• counterclockwise - the direction opposite from the way  hands of a clock move
• acute angle - an angle that has a measure greater than 0° and less than 90°
