Find the length of the garden and width of the garden

The rows and columns of lattice points in a three-by-three square array are evenly spaced one unit apart. how many distinct triangles with at least one side of length 2 units can be drawn using three lattice points for the vertices?

M.xyz =radians. covert this radian measure to its equivalent measure in degrees.
