Question

The sides of a triangle are 15cm, 10cm and 25cm. Determine if it

is a right triangle​

Answer 1

Step-by-step explanation:

it's not a right angle triangle

Answer 2

Step-by-step explanation:

We know that if it is a right angled triangle,

sum of square of 2 sides is equal to the square of the other side ...Pythagorus Thm.

Here, let's name the sides AB, BC and CA respectively.

Therefore,

AB^2= (15)^2= 225cm

BC^2= (10)^2= 100cm

CA^2= (25)^2= 625cm

Here,

Pythagorus Thm. cannot be shown in any way.

i.e.

Either AB^2+BC^2= CA^2

Or AB^2+CA^2= BC^2

Or BC^2+CA^2= AC^2

Thus, tri. ABC is not a right triangle.
