Construct a right triangle whose base is 12 cm and sum of its hypotenuse and other side is 18 cm.

The below given steps will be followed to construct the required triangle.

Step I:- Draw line segment AB of 12 cm. Draw a ray AX making 90° with AB.

Step II:- Cut a line segment AD of 18 cm (as the sum of the other two sides is 18) from ray AX.

Step III:- Join DB and make an angle DBY equal to ADB.

Step IV:- Let BY intersect AX at C. Join AC, BC.

ΔABC is the required triangle.
