13. Mark everything that is correct about triangles.

They have three sides

An acute angle on a triangle can be up to 100' before it becomes a right angle.

Every angle on a triangle has to be at least 10'

They are ALWAYS either equilateral, isosceles, or scalene triangles.

Every angle on a triangle has to be less then 100'

Triangles don't have to have three angles

Every angle on a triangle has to be less than 180'

The smallest an obese angle on a triangle can be is 80' degrees because a right angle is 80'.

They have three angles

All triangles have three sides except for a diagron triangle, which has three and a half sides.
