Question

. Is a triangle with sides of length 6 ft., 21 ft., 23 ft. a right triangle?
Show how you know.

Answer 1

Answer:

No

Step-by-step explanation:

Because, If we take Hypotenuse formula ie., Pythagorus Theorem.

The longest side is Hypotenuse ie., 23

And other two sides can be considered as Opposite and Adjacent

ie., 21 and 6

So, By Pythagorus Theorem

H$H^{2}=O^{2}+A{2}$

$23^{2} = 21^{2} + 6^{2} \\23^{2} - 21^{2} = 6^{2} \\529-441 = 36$

So 88 = 36

Lhs is not equal to Rhs

so not a right angle triangle

Hope u got ur answer
