Question

the side of triangle is 3cm 4cm 5cm find out is it right angled triangle ​

Answer 1

Answer:

Step-by-step explanation:

given , the sides of the triangle 3cm 4cm and 5cm

of which the side having the greater measurement is taken to be the hypotenuse.

so, lets check whether the given measurements satisfy the pythagorous theorem.

In a right angled triangle, the square of the hypotenuse will be equal to sum of the squares of the other 2 sides.

ie.,

5² = 3²+4²

=> 25 = 9+16

=> 25 = 25

pythagorous theorem holds true .

and hence the given measurements forms a right angled triangle.

Answer 2

Answer:

Yes, it is a right angle triangle

Step-by-step explanation:

Hypotenuse = Greatest side = 5cm

$5\: = \: \sqrt{ {p}^{2} + {b}^{2} } \\ 5= \sqrt{ {3}^{2} + {4}^{2} } \\ 5= \sqrt{9 + 16} \\ 5 = \sqrt{25} = 5 \\ hence \: it \: is \: a \: right \: angle \: triangle$
