Question

3) Which of these can be the lengths of the sides of a right angled triangle?
(1) 12, 16, 20 (in cm)
(ii) 5, 12, 14 (in mm)​

Answer 1

Answer:

12,16 , 20  and 5,12,14 can be the sides of a right angled triangle.

Step-by-step explanation:

We first need to find the square of 12 and 16 and then add them up. After we add up we get the answer as 400. And then we find the square root of 400 which is 20.

just the difference is that it is in cm and mm.

Answer 2

Answer:

1)12,16,20 only.after adding sqr of 12(144) and 16(256)=400,sqrt(400)=20.which is satisfied the right angle triangle condition.
