1. USING APROTRACTORBy Maria AdroverGeometry 4th_Unit 2_Angles

2. MEASURING ANGLESSet the protractor so that:The vertex of the angle match the protractor centre.One angle arm should match the base line.Read the score, this is the angle measure. 3. TIP!!If the arms of the angles are too short...- Make them longer using a ruler and a pencil.- Now you can measure it!! 4. DRAWING ANGLESDraw a straight line (using a ruler) starting from an A point.Match the protractor centre with the A pointLook for the measure (angle degrees) in the protractor scoreand mark it as point B.Draw a straight line matching the two points (A--B)
