A triangle has three internal angles and three external angles, for a total of six angles.
Every triangle has three angles that total 180o. In an equilateral triangle, there are three 60o angles.
No. The sum of the three interior angles of a triangle will always be 180 degrees.
No. The three interior angles of any triangle, no matterwhat shape it is, always total 180 degrees.
A triangle with three congruent angles
Every triangle has three interior angles which total 180 degrees. A right triangle has one of the angles as 90 degrees.
The triangle has three exterior angles. Added together, their total is 180 degrees.(Same as the total of the three interior angles when they're added together.)
A triangle can never have three right angles
That is the definition of a triangle. If it did not have three sides it would not be a triangle. If it did not have three angles, it would not be a triangle.
A triangle has three angles.
