Question

which of the following can be the sides of a right triangle
2.5 ,6.5,6cm​

Answer 1

Answer:

I) as you can see 2.5^2+6^2=6.5^2

L.h.s=2.5^2+6^2

= 6.25+36

=42.25

=6.5^2=r.h.s

Therefore right angle triangle

2) 2^2+2^2=8 and 5^2=25

They are not equal, therefore not right angle triangle

3) 1.5^2+2^2=2.25+4

=6.25

=2.5^2

Therefore it is a right angle triangle

Answer 2

WE KNOW THAT,

HYPOTNUSE IS THE LARGEST SIDE.

SO, HYPOTNUSE IS 6.5 CM.

(H)^2 = (P)^2 + (B)^2

(6.5)^2 = (2.5)^2 + (6)^2

42.25 = 6.25 + 36

42.25 = 42.25

L.H.S = R.H.S

HENCE, PROVED....
