Question

Construct a triangle KLM IF KL+LM+ MK=11.5cm
angle L=50
angle M=70

Answer 1

•Draw a line segment XY of 11.5cm
•From X draw an angle of 50° and then draw its angle bisector and name the ray obtained as XA
•Similarly from Y draw an angle of 70° and draw its angle bisector and name the ray obtained as YB
•Extend XA and YB such that they meet each other at K.
•Now draw perpendicular bisector of KX and KY .
• The point obtained on line segment XY by the perpendicular bisector of KX will be point L and the point obtained by the perpendicular bisector of KY will be point M.
•Join KLM.

Answer 2

first draw aline 11•5cm then draw 50 by protactor and draw 70 by protactor bisects these angles and produce both lines and drAw perpendicular bisector
