1. Draw a pair of tangents to a circle of radius 5 cm which are inclined to each other at an angle of 50 degree.
2, If D, E and F are mid points of of side BC, ACand AB of a triangle ABC respectively where the coordinates of A , B & C are respectively (6,-2), (0,-6) & (4,8). Then using coordinate geometry prove that area of trangle ABC equalls to Four times the area of triangle DEF.
