Question

The length of three sides of a triangle are given below.Find Which can form a right triangle.​

Answer 1

Answer:

Option a, Option b and option d can form a right angled triangle

Step-by-step explanation:

a) 6.5 cm is the longest side (Hypotenuse)

(2.5)² + 6² = 6.5²

6.25 + 36 = 42.25

42.25 = 42.25

b) 61 cm is the longest side

11² + 60² = 61²

121 + 3600 = 3721

3721 = 3721

c) 2² + 2² = 5²

4 + 4 = 25

8 is not equal to 25

d) 3.5 is the largest side.

2.1² + 2.8² = 3.5²

4.41 + 7.84 = 12.25

12.25 = 12.25

So Options are A, B, D
