180
180 dregress
180 degrees
180 degrees in an equilateral triangle.
A right triangle.
300 degress
180 - (80 + 60) ie 40
Square, Rectangle, Right Triangle...
The 3 interior angles of any triangle add up to 180 degrees.
anything over 180, A triangle is composed of 180 degrees, so if one angle alone is 180 degress then the shape is not A triangle.
its a triangle has 1 obtuse angle greater than 90 degress it also scalene NO equal sides
