Question

Construct a right triangle ∆ABC in which C = 90 degree ,BC = 3 cm, AC + AB =5cm.

Answer 1

Answer:

In triangle in △ ABC, by Pythagoras theorem

AC ²=AB ²+AC ²

Given, AB=5 cm, BC=x

5²=x² +3²

=x ²=5²−3²

=25−9=16

x= 16

Or

=4 cm

Hence, AB=4 cm.

Or

Simply after constructing, we can measure AB side.
