Given an angle a, what figure can you construct using the steps below?
step 1: draw a ray with endpoint s.
step 2: with the compass point on vertex a, draw an arc that intersects the side of step 3: with the same compass setting, put the compass point on point s. draw an arc and label its point of intersection with the ray as r.
step 4: open the compass to the length bc. keeping the same compass setting, put the compass point on r. draw an arc to locate point t.
step 5: draw st (arrow pointing to the right, above them).
a. a perpendicular bisector
b. a congruent segment
c. an angle bisector
d. a congruent angle
