A. If a + b = c, draw the two shorter sides, a and b, with a right angle between them. The third side will fit to form a triangle. B. If a2 + b2 = c2, draw any two of the sides with a right angle between them. The third side will fit to form a triangle. C. If a, b, and c are the sides of a triangle, draw a and b as the two shortest sides and c as the longest side. If c > a + b, then the triangle formed is a right triangle. D. If a2 + b2 = c2, draw the two shorter sides, a and b, with a right angle between them. The third side, c, will fit to form a triangle.
