Question

Construct a triangle ABC in which AB=BC=3cm and B=90°
write the steps of construction.​

Answer 1

Answer:

In triangle in △ ABC, by Pythagoras theorem

AC^2

=AB^2+AC^2

Given, AB=5 cm, BC=x

5^2=x^2+3^2

x^2=5^2−3^2

=25−9=16

x= 16

=4 cm

Hence, AB=4 cm.

Or

Simply after constructing, we can measure AB side.
