A student draws a triangle to scale using side lengths 8, 16, and 18. Can the student conclude that this is a right triangle?

This triangle is not a right triangle

Explanation:

To find this you can use the set up for the pythagorean theorem. The hypotenuse is the c while the other sides are a and b.

After setting it up you add in the numbers

Then square them

Then you add the two sides together

If they are equal then it is a right triangle. While if they are not equal it is either obtuse or acute.

Sorry if this is long or doesn't make sense.
