Answer:

OA P Q R B C 90°

Step by Step Explanation:
  1. Draw a ray ^@OA^@. OA
  2. With ^@O^@ as the center and any convenient radius, draw an arc, cutting ^@OA^@ at ^@P^@. OA P
  3. With ^@P^@ as the center and the same radius, draw an arc, cutting the arc drawn in step 2 at ^@Q^@. OA PQ
  4. With ^@Q^@ as the center and the same radius, draw an arc, cutting the arc drawn in step 2 at ^@R^@. OA PQR
  5. With ^@Q^@ as the center and the same radius, draw an arc. OA P Q R
  6. With ^@R^@ as the center and the same radius, draw an arc, cutting the arc drawn in the previous step at ^@B^@. OA P Q R B
  7. Draw ^@OB^@ and produce it to ^@C^@.^@\angle AOC^@ is the angle of measure ^@90^\circ^@. OA P Q R B C 90°
