Using ruler and compass only, draw a right angle.


Answer:

OA P Q R B C 90°

Step by Step Explanation:
  1. Draw a ray OAOA. OA
  2. With OO as the center and any convenient radius, draw an arc, cutting OAOA at PP. OA P
  3. With PP as the center and the same radius, draw an arc, cutting the arc drawn in step 2 at QQ. OA PQ
  4. With QQ as the center and the same radius, draw an arc, cutting the arc drawn in step 2 at RR. OA PQR
  5. With QQ as the center and the same radius, draw an arc. OA P Q R
  6. With RR as the center and the same radius, draw an arc, cutting the arc drawn in the previous step at BB. OA P Q R B
  7. Draw OBOB and produce it to CC.AOCAOC is the angle of measure 9090. OA P Q R B C 90°
