Question

determine wheather the triangle whose leangths of sides are 3 cm , 4 cm , 5 cm , is a right angled triangle​

Answer 1

Step-by-step explanation:

Since all three sides have different lengths, it is a scalene triangle. But, we must test for a second feature. Using Pythagorus' theorem

a^2+b^2=c^2

we find

3^2+4^2=5^2

9 + 16 = 25

So, these sides also cause it to be a right triangle.

Answer 2

Step-by-step explanation:

Lengths of triangle are 3cm,4cm,5cm.

Where as p=3cm,b=4cm,h=5cm.

For right angled triangle , p^2+b^2=h^2.

So,3^2+4^2=5^2

=9+16=25

=25=25

Here,we know yes,it is the right angled triangle .
