Question

please find no 1 5 cm 8 cm 10cm​

Answer 1

Answer:

It is not a right angled triangle.

Step-by-step explanation:

Among 5cm, 8cm and 10 cm.

The longest side will be hypotenuse.

so, according to Pythagorous theorem :

$Hypotenuse^{2}\:=\: Perpendicular^{2}\:+\:base^{2}$

$10^{2}\:=\:8^{2}\:+\:5^{2}$

$100\:=\:64+25$

$100\:=\:89$ (LHS not equal to RHS)

As you see, Square of the hypotenuse is not equal to sum of square of other two sides.
