Question

Felipe is making triangles for a stained glass window, he made the design shown but wants to change it. Felipe wants to move the purple triangle to the corner. The purple piece has side lengths of 4.5 inches, 6 inches, and 7 inches. Can the purple piece be moved to the corner?

Answer 1

We have sides of triangle as
`4.5` inches,
`6` inches and
`7` inches.

So the sum of square of two smallest side is-

`=4.5^2+6^2`


`=20.25+36`


`=56.25`

Now lets find the value of square of longest side of triangle-

`=7^2`


`=49`

Now from both value

`49`
`\\eq`
`56.25`


`7^2`
`\\eq`
`4.5^2+6^2`

So from Pythagoras theorem the given triangle is not a right triangle so it can not moved to the corner.

Thus, Since the triangle is not a right triangle therefore it can not moved to the corner.
