उत्तर
Construction:
Step 1: Drawn a line. Marked A and B on the line such that AB = 7 cm.
Step 2: At A, drawn a ray AX making an angle of 120° with AB.
Step 3: With A as centre, drawn an arc of radius 6.5 cm to cut the ray AX.
Marked the point of intersection as C.
Step 4: Joined BC.
ABC is the required triangle.
