Sides of triangles are given below. Determine which of them are right triangles.In case of a right triangle, write the length of its hypotenuse.
(1) 7 cm, 24 cm, 25 cm
(ii) 3 cm, 8 cm, 6 cm
(iii) 50 cm, 80 cm, 100 cm (iv) 13 cm, 12 cm, 5 cm

Step-by-step explanation:
to prove that the triangles are right angled ,we use Pythagoras theorem so,
1) (7×7)+(24×24)=(25×24)
49+576=625
625=625
since LHS =RHS
therefore this triangle in right angled.
now you can do the other parts yourself.
hope this will help you!!!!!!

Step-by-step explanation:7²=49, 24²=576, 25²=625largest no. is 25²=625 ---(1)7²+24²= 49+5767²+24²=625 ---(2)from 1 and 225²=7²+24²this right angle triangle In this way you can Determine which of them are right triangles.
You can use the another method is:hypotenuse² = base² + height²25²=7²+24²625=49+576 625=625 from this we find this is a right angled triangle and the length of its hypotenuse.
I hope it's helps .....and try to solve another example also
