Answer 1

Answer:

(i)It is a right angled triangle (ii) It is not a right angled triangle (iii) It is not a right angled triangle (iv) It is a right angled triangle

Step-by-step explanation:

We can do this by using Pythagoras theorem:

(i) 7²+24²=25²

49+576=625

625=625

Therefore, it is a right angled triangle.

(ii)3²+6²≠8²

9+36≠64

45≠64

Therefore, it is not a right angled triangle.

(iii)50²+80²≠100²

2500+6400≠10000

8900≠10000

Therefore, it is not a right angled triangle.

(iv)12²+5²=13²

144+25=169

169=169

Therefore, it is a right angled triangle.

Answer 2

(i)7^2+24^2=625

25^2=625

so, right angle triangle.

(ii)3^2+6^2=45

8^2=64

so, is not a right angle triangle.

(iii)50^+80^2=8900

100^2=10000

so, is not a right angle triangle.

(iv)12^2+5^2=169

13^2=169

so, right angle triangle.
