Question

if 5 cm, 12 cm and 13 cm are the sides of a triangle check it
if it is right angled triangle​

Answer 1

Answer:

to find whether 3 measurments form a right triangle

we need to change whether (base)²+(height)²=(hypotenuse)²

          here LHS =5²+12² = 25+144 = 169

                  RHS = 13²      = 169

therefore LHS=RHS

and the given measures will for a right angles triangle.

Answer 2

Yes it is a right triangle

Because

√13^2 - √12^2

=√ 169 - √144

=√ 25

=5
