As shown in the figure, given the line segments C and B (c > b), calculate: △ ABC, so that ∠ C = 90 °, ab = C, AC = B. (ruler drawing)

First of all, make the middle vertical line of line C to determine the position of the middle point. Then make a semicircle with C as the diameter, and make a circle with radius length B with point a as the center. The intersection of the circle and semicircle is the position of point C. the triangle is made
