For an isosceles right angles triangle having each of equal sides ‘a’ , we have I. Area = a 2 II. Perimeter = (2 + )a III. Hypotenuse = 2a Which of the following is true?

Question

Philoid · Accepted Answer

We know that,

Area of triangle =

=

Now, Hypotenuse =

=

Perimeter = a + a +

= 2a +

= a (2 + )

∴ I and II are true

Hence, option (c) is correct
