If a triangle has sides of 8,11, and 13. Is it a right triangle?

If a² + b² = c², then the triangle is right.

So we have (8)² + (11)²  ?  (13)²

(8)² is 64, (11)² is 121, and (13)² is 169.

So we have 64 + 121 ? 169

64 + 121 is 185 and we can see that 185 > 169.

This triangle would not be a right triangle.

In fact, it would be an acute triangle.

So no, it's not a right triangle.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
