The base of an isosceles triangle is 6cm and each of its equal sides is 5cm. The height of the triangle is –
It is given in the question that,
Base of the isosceles triangle = b = 6 cm
Two equal sides = a = 5 cm
We know that,
Height of an isosceles triangle = 
= 
= 
= 
= 
= 4 cm
Hence, option (c) is correct
