Question

in triangle LMN ,L=10cm,m=24cm,n=27state wheather triangle is a right angled triangke or not​

Answer 1

Answer:

to check whether a triangle is right angled or not we have to check if the square of longest side is equal to the sum of square of other sides.

n² = (27)² = 729

and l² = (10)² = 100

m² = (24)² = 576

since 100 + 576 is not equal to 729 , the triangle is not a right angled triangle.
