WebSteps of Construction: Step 1: First of all, draw the base BC and at the point B make an∠XBC equal to the given angle. Step 2: From the ray BX, cut the line segment BD = AB + AC. Step 3: Join DC now which make ∠DCY = ∠BDC. Step 4: When CY intersect BX at A then it form the required triangle i.e. ABC.
