"Measurement of Angles" Preliminary PPT Courseware for Graphic Understanding 2

Use a ruler to draw angles

Take O as the center of the circle and draw an arc with an appropriate length as the radius. The two sides of the intersection angle are at two points C and D;

Draw ray EF, take E as the center, draw an arc with the same length as the radius, and intersect ray EF at point G;

Draw an arc with C as the center and the length of line segment CD as the radius;

Then take point G as the center of the circle, draw an arc with the same length as the radius, and intersect the original arc at point H;

Draw ray EH.
