Question

Check whether the following triangles are right angled triangle (1) 8 cm, 6 cm, 12 cm

Answer 1

verify: a triangle is right angled or not?

solution:

we know for the right angled triangle it follows pythagorean property

`(hypotenuse)^2=(base)^2\text{ +\lparen pe}rpendicular\rparen^2`

from the figure,

`\begin{gathered} (12)^2=(8)^2+(6)^2 \\ =64+36 \\ =100 \end{gathered}`

but we know square of 12 is 144.

Hence, it not a right angled triangle.
