Question

Does the following make a right triangle?

A ceramic tile with sides 20 cm, 21 cm, and 29 cm


A. yes
B. no

Answer 1

yes

Explanation:

In order for it to be a right triangle, it has to be
`a^2+b^2=c^2`.

`20^2+21^2` should equal
`29^2`

400+441 should equal 841

So yes, the lengths make a right triange.
