Answer:

2nd one is the answer for this

Answer 2

Answer:

(I) by Pythagoras theorem,

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

thus it forms right angle triangle

(2) similarly, if we apply

2^2+2^2 is not equal to 5^2

thus it doesn't form right angle triangle

(3) similarly if we apply 1.5^2 +2^2=2.5^2

thus it forms a right angle triangle
