Question

Question 1 (iv)
Sides of triangles are given below. Determine whether it forms a right triangle? In case of a right triangle, write the length of its hypotenuse.
(iv) 13 cm, 12 cm, 5 cm

Answer 1

(iv) Given that sides are 13 cm, 12 cm, and 5 cm.
Squaring the lengths of these sides, we will get 169, 144, and 25.
Clearly, 144 +25 = 169
Or, ${12}^2+5^2={13}^2$
The sides of the given triangle are satisfying Pythagoras theorem.
Therefore, it is a right triangle.
Length of the hypotenuse of this triangle is 13 cm.
