Question

In Pythagorean theorem is the purple triangle a right triangle
15.5m , 14.0m, 20.8m

Answer 1

Answer: No. It is not a right triangle.

Explanation:

240.25 + 196 = 436.25

`\sqrt436.25` = 20.8865986

20.8865986 does not equal 20.8, therefore:

`15.5^2+14^2\\eq 20.8^2`

I hope this helps!
