Question

in ΔLMN l=5,M=13,N=12.state whether ΔLMN is a right angle triangle or not
​

Answer 1

Step-by-step explanation:

In the right a gle triangle the sum of squares of 2 angles will be equal to the square of the third side

L^2 + N ^2 = M ^2

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

25 + 144 = 169

169 = 169

hence ,

LMN is a right angle triangle
