at a) paint the figure horizontal on the right side. P becomes P´
b) paint the figure A one step clochwise arround P. 60° is one angle of the triangles. All angles in a triangle are together 180°. so we have 3 angles with same size so 180°/3=60°
c) go two triangles to the left and paint the same figure A as on the left side of l.
Slope formula y2-y1/ x2-x1 = 3/5
I cannot read the screenshot :/
