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
