Step One: Draw a ray with endpoint S. Step Two: With the compass on vertex A, draw an arc that intersects the sides of A. Label the points of intersection B and C. Step Three: 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.
