For an isosceles triangle having base b and each of the equal sides as a, we have:
I. Area =
II. Perimeter = (2a +b)
III. Height =
Which of the following is true?
According to question, we have:
Base of triangle = b
Equal sides of triangle = a
∴ Area =
Perimeter = (2a + b)
And, Height =
∴ I, II and III are true
Hence, option (d) is correct
