### Geometry1.10 Classifying Angles

 Acute Angle: An angle whose measure is less than 90 degrees and greater then zero degrees is called an acute angle. 00 < mĐA < 900 Right Angle: An angle whose measure is 90 degrees is called right angle. mĐA = 900 Obtuse Angle: An angle whose measure is greater than 90 degrees and less than 180 degrees is called obtuse angle. 900 < mĐA < 1800 Straight Angle: An angle whose measure is 180 degrees called a straight angle. mĐA = 1800 Reflex Angle: An angle whose measure is greater than 180 degrees and less than 360 degrees is called a reflex angle. 1800 < mĐA < 3600 Complete Angle: An angle whose measure is 360 degrees is called a complete angle. mĐA = 3600 Zero Angle: If the measure of an angle is zero it is called a zero angle. mĐA = 00 Directions: Answer the following questions. Also draw kinds of angles, measure them using a protractor and label them.
