Steps of Construction:
Step 1: Draw a line l.
Step 2: Draw an angle of 90° at M on l
Step 3: Cut an arc of radius 3 cm on the perpendicular. Mark the point as A
Step 4: With A as center, make an angle of 30° and let it cut l at C. We get ∠ACB = 60°.
Step 5: Cut an arc of 5 cm from C on l and mark the point as B.
Step 6: Join AB..
Thus, △ABC is obtained
Step 7: Extend AB to D, such that BD = BC.
Step 8: Draw DE || BC, cutting AC produced to E.
Then, △ADE is the required triangle, each of whose sides is of the corresponding sides of △ABC.
