Easy points! Please help! Thanksss

No

Step-by-step explanation:

You can check to see if the triangle is a right triangle or not by using the pythagorean theorem, which is a^2+b^2=c^2.

C is always the hypotenuse, which is the longest side of the triangle. So plug in 6 and 8 for a and b and 9 for c. Square them, and if the sum of a and b equals what c is, then it is a right triangle. Otherwise, it is not.

So let's check this triangle.

6^2+8^2= ?

36 + 64 = 100

9^2 is 81.

36 + 64 does not equal 81, so this is not a right triangle.

-20?

Step-by-step explanation:

if u divide -20 by -20 it equals POSITIVE 1.
