How to construct a triangle with 62mm 55mm and 9 cm side?

Answer 1

1. Using a ruler, draw a straight line, AB, of length 9 cm = 90 mm.
2. Place a pair of compasses, opened to 62 mm, at A and draw an arc above AB.
3. Place a pair of compasses, opened to 55 mm, at B and draw an arc to intersect the previous arc at C.

Then ABC is the required triangle.
