NamePractice SheetReading aprotractor tomeasure anglesReading a ProtractorA protractor is a tool used to measure angles (in degrees).When using a protractor, it is important to first classify the angle:(Nearest 10 ) Acute angle This angle should have a measure less than 90 . Obtuse angle This angle should have a measure greater than 90 .Angle 1 is an acute angle.- The measure must be less than 90 .Angle 2 is an obtuse angle.- The measure must be more than 90 .The ray lands on the 30 and 150 mark.Angle 1 is acute, so the measure is 30 .The ray lands on the 50 and 130 mark.Angle 2 is obtuse, so the measure is 130 .Classify each angle below. Then, measure using the protractor.1.2.Type of Angle Measure Type of Angle Measure 3.4.Type of Angle Measure Type of Angle Measure 2015 Kathleen& Mande’4.MD.6-7 Pg.1
