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'

• A right angle on a triangle is 90', so the biggest an acute angle on a triangle can be is 90'

• 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.
