Make a IDENTICAL copy of an angle using only paper, a compass and a straightedge.
Draw a ray with endpoint D. Step 2 Draw an arc that intersects both rays of ∠A. Label the intersections B and C. Step 3 Draw the same arc on the ray. Label the point of intersection E. Step 4 Set the compass to the length BC. Step 5 Place the compass at E and draw a new arc. Label the intersection of the new arc F. Draw ‾ →DF . ∠D is congruent to ∠A.
