Question

The sides of ∆LMN are 5 cm, 13 cm and 12cm state whether it is a right angled triangle

or not.​

Answer 1

We know the Pythagoras theorem states the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle. It is satisfying the Pythagoras theorem, thus the given triangle is a right-angled triangle. Thus, the hypotenuse is 13 cm, base is 5 cm and height is 2 cm.

Answer 2

Answer:

yes it is right angled triangle.

Step-by-step explanation:

12^2+5^2=13^2(Pythagoras theorem)

144+25=169

169=169.

Therefore it is right angled triangle.
