To work these things out,first you have to measure the outside of the triangle. your triangles may be different sizes but mine at school was 30 inches long which is large.Once you measured your triangle,work out how much angles the triangle could hold/fit.You have to have angles that are 10 inches long and another 10 inches high for the opening part.Now count how many angles you have.At school mine had 6 angles in the triangle.With the number of angles add double that number then see what number you get.For example,you had the number 10 so you double it which makes 20.So you have the starting number of your diameter which from instruction 4 is 20.Then using your number count how many times it can get to the number 100.For example,i had the number 20 so then i count it by 20's like this:20,40,60 and so on. I would end up with 5 turns with the number 20.then add 5 to the number you have and that's how much the diameter is of an exterior triangle in angles!so mine would be 25!Thankyou,i had fun explaining to you!see you next time!

Interior Angles of a Triangle: 60 Exterior Angles of a Triangle: 120 Interior Angles of a Heptagon 128 (approx) Exterior Angles of A Heptagon 52 (approx) Answer: Triangle
The 3 exterior angles of any triangle add up to 360 degrees
It's when you add up the exterior angles for an obtuse triangle.
The exterior sum of the angles of any polygon including a triangle is always 360 degrees.
The exterior angles of a triangle add up to 360 degrees.
Actually, no. The sum of the exterior angles of a triangle is 360 degrees. The sum of the interior angles of a triangle is 180 degrees.
The interior angles of a triangle add up to 180 degrees. The exterior angles of a triangle add up to 360 degrees.
The sum of the interior angles of any triangle is 180 degrees.
The exterior angles of a triangle add up to 360 degrees.
An exterior angle of a triangle can have a value between (but not including) 0 to 180 degrees.
