Question

State whether 2 cm, 2 cm and 5 cm forms a right angled triangle or not give the reason.​

Answer 1

Answer:

NO it is not a right angled triangle

Step-by-step explanation:

if ΔABC is a right angled triangle then the longest side is equal to the Hypotenuse

since, 5cm is the longest side

therefore,

(5)²=(2)² + (2)²

25 = 4 + 4

25 = 8

therefore, Δ ABC is not a right angled triangle because as the property states, the square of the longest side is equal to the square of the other two sides.Pleas tell me if you liked the answer
