Answer:
Steps of construction:
Draw a line AB = 7 cm
Taking P ascentre and same radius, draw an arc of a circle which intersects AB at M.
Taking M ascentre and with the same radius as before drawn an arc intersecting previously drawn arc, at point N.
Draw the ray AX passing through N, then
Taking A ascentre and radius equal to 5 cm, draw an arc cutting AX at C.
Join BC
The required triangle ABC is obtained.
Draw angle bisector of∠CAB and ∠ABC
Mark their intersection as O
With O as center, draw a circle with radius OD
