Construct a right triangle with a hypotenuse of length 17 and a leg of length 8.
1. Select the SEGMENT WITH GIVEN LENGTH 
tool, and enter a length of 8.
2. Select the PERPENDICULAR LINE 
tool. Click on segment AB and then on point A.
3. Select the CIRCLE: CENTER & RADIUS 
tool. Click points B, and enter a radius of 17.
