How could we construct an angle tester with right angles and half right angles? How could we construct an angle tester with right angles and thirds of right angles? How could we use the angle testers to test 2 line angles as the relative slant of 2 arms that meet at a vertex on shapes as right angles acute angles or obtuse angles? How could we construct an angle tester using a straw and a chenille stick? How could we use the angle tester to test 2 line angles as the amount of turn around a vertex as right angles acute angles or obtuse angles? How could we use the angle testers to test 1 line angles as the amount of turn around a vertex as right angles acute angles or obtuse angles? I folded my paper to create angles by … I turned the arms of my angle tester to make angles by … I tested the size of 2 line angles on shapes by … The arms meet at the vertex. The arms have different slants. I tested the 2 and 1 line angles on the scissors or the clock by … The arms turn around the vertex. The angle is a right angle / an acute angle / an obtuse angle because … Measurement and Geometry 40
