Follow the following steps of constructions: (a) Draw a line l and mention a point O on it. (b) With O as center and a short radius, draw an arc that cuts line l at A. (c) With A as center and the same radius (as in step 2), draw an arc that cuts the first arc at B. (d) Join O and B. Extend OB to get a ray. What is the measure of ∠AOB (in degrees)?
