Question

using a ruler and a pair of compass only. Construct ABC such that angle ABC=90°,AB=5cm and BC=6cm.Measure AC

Answer 1

you can construct a right angle by constructing a perpendicular bisector.

Or, google will show you many other ways.

Then just measure your distances.

Answer 2

Use ruler and a pair of compass only to construct triangle ABC in wh /AB/ =7.5cm /BC/=6cm and /ABC=45°

Answer 3

Construct∆ABC such that<ABC=90,|AB|=5cm and |BC|=6cm.Measure |AC|.
