The sum of the three angles in any triangle is 180 degrees. In plane Euclidean geometry
That's not possible.Two interior angles of a triangle can't add up to 261°, because all three of the interior anglesin any triangle always add up to 180°.
There are three angles in a triangle but to measure them you would use a protractor.
The three interior angles add up to 180°. (180° is the measure of a triangle)
an equilateral triangle :)
An equalateral triangle
It is an equiangular triangle it is correct.
An equilateral triangle has three equal sides. The angles of an equilateral triangle measure 60 degrees each, but the sides can be any length.
Isosceles Triangle
It is a scalene triangle
It is 60 degrees and it is an equilateral triangle.
state if the three numbers can be measures of the sides of a triangle. show your work 1- 15,12,9
All three sides (and therefore angles) in an equilateral triangle are the same measure. All three sides (and therefore angles) in a scalene triangle are different.
