- 13.Mark everything that is correct about triangles.
- A.
They have three sides
- B.
An acute angle on a triangle can be up to 100' before it becomes a right angle.
- C.
Every angle on a triangle has to be at least 10'
- D.
A right angle on a triangle is 90', so the biggest an acute angle on a triangle can be is 90'
- E.
They are ALWAYS either equilateral, isosceles, or scalene triangles.
- F.
Every angle on a triangle has to be less then 100'
- G.
Triangles don't have to have three angles
- H.
Every angle on a triangle has to be less than 180'
- I.
The smallest an obese angle on a triangle can be is 80' degrees because a right angle is 80'.
- J.
They have three angles
- K.
All triangles have three sides except for a diagron triangle, which has three and a half sides.
