The diagram is not to scale and I didn't measure the angles I just want to know if I have the angles you gave between the correct sides. Write back and let me know. Michelle wrote back Yes that is what it looks like. It's a culdasac. Thanks! Michelle Now that I am certain I have the angles in the correct places I can use our size caculator for foursided lots. I labeled the verticies clockwise as instructed and input the lengths of the four sides and the angle at C as 50^{o}. The result was 0.19 acres. I then redid the calculations with the angle at D as 153.3^{o}. The result was 0.21 acres. I expected closer agreement. The best I can say is that the area is 0.2 acres. Harley
