step 1:
draw a obtuse scalene triangle side a = 76.5 side b = 58 side c = 35

step 2:
draw a obtuse scalene triangle side a = 76.5 side b = 58 side c = 35 assign corner variables and calculate the Vertex coordinates

step 3:
draw a obtuse scalene triangle side a = 76.5 side b = 58 side c = 35 assign corner variables and calculate the Vertex coordinates then draw another obtuse scalene triangle using the corners A and B fix in the location they are in but moving corner C down 77 and left 25
