For an isosceles triangle having base = 12 cm and each of the equal sides equal to 10 cm, the height is

Let us assume ABC be an isosceles triangle having,

Base, AC = 12 cm

AB = AC = 10 cm

BD =

=

= 6 cm

We know that,

In right angled triangle, ABC

AD =

=

=

=

= 8 cm

Thus, height of the triangle is 8 cm

Hence, option (d) is correct
