Because two of the triangles are identical, you can simply multiply the area of the first triangle by two: 2A1 = 2 (½bh) = 2 (½ab) = ab. The area of the third triangle is A2 = ½bh = ½c*c = ½c2. The total area of the trapezoid is A1 + A2 = ab + ½c2. 5.1. Define two points in the X-Y plane. The Pythagorean Theorem can easily be used to calculate the straight-line distance between two points in the X-Y plane. All you need to know are the x and y coordinates of any two points.
