Answer 1

Answer:

I) here hypotenuse=6.5 cm

6^2+2.5^2

=36+6.25

=42.25

=(6.5)^2

so it is a right angle triangle

ii) hypotenuse=5 cm

2^2+2^2

=4+4

=8

is not equal to 5^2

it is not a right angle triangle

iii)

hypotenuse=2.5 cm

1.5^2+2^2

=2.25+4

=6.25

=2.5^2

it is a right angle triangle
