construct a triangleABC if its perimeter is 10.4cm and base angles 45degree and120degree
Steps of construction of a triangle when perimeter and base angles are given.
1)Draw XY = 10.4 cm
2)Draw LXY = 45 and MYX = 120
3)Draw angle bisector of LXY
4)Draw angle bisector of MYX such that it meets the angle bisector of LXY at point A.
5)Draw the perpendicular bisector of AX such that it meets XY at B
6)Draw the perpendicular bisector of AY such that it meets XY at C.
7)Join AB and AC.
Thus ABC is the required triangle.
