To construct a triangle ABC in which ∠B=60∘,∠C=45∘ and AB + BC + AC = 12 cm
The steps of construction are:
Step 1: Draw a line segment XY=12 cm
Step 2: At X, construct an angle of 60∘ and at y construct an angle of 45∘
Step 3: Bisect these angles.Let bisector of these angles intersect at point A
Step 4 will be
Step 4: Draw perpendicular bisector PQ of XA to intersect XY at B and RS of YA to intersect XY at C.
