Which of the following can be the sides of a right triangle?

2 cm, 2 cm, 5 cm

In the case of right-angled triangles, identify the right angles.

Solution

2 cm, 2 cm, 5 cm

(2)2 = 4

(2)2 = 4

(5)2 = 25

Here, (2)2 + (2)2 ≠ (5)2

The square of the length of one side is not equal to the sum of the squares of the lengths of the remaining two sides. Hence, these sides are not of a right-angled triangle.

  Is there an error in this question or solution?
