Question:-

ΔABC is an isosceles triangle in which ∠C= 90° . If AC = 6 cm, then AB=

A. 6√2 cm

B. 6 cm

C. 2√6 cm

D. 4√2cm

Answer:-

In triangle ABC

Let tge altitude be AD on BC

AC=25cm

AB=25cm

BC=14cm

Therefore DC= 1/2*BC

=1/2*14

=7

By Pythagoras theorem,

AD^2+CD^2=AC^2

AD^2+7^2=25^2

AD^2+49=625

AD^2=625-49

AD^2=576

AD=24

Therefore altitude from A on BC is 24 cm
