The 3 interior angles of any triangle add up to 180 degrees.
A triangle is a polygonal shape, not an angle and therefore, cannot have a supplementary angle.
The supplementary angle of the triangle.
They are called supplementary angles.
always
A supplementary angle is a 180-degree angle minus the number of degrees in the given angle.
180
140
A supplementary angle is 180 degrees. So, it depends how many supplementary angles you add together.
90 degrees
Its supplementary angle is 121 degrees
Angles are said to be supplementary when they add up to 180 degrees.
135 degrees. Supplementary angles add up to 180 degrees so the supplementary to 45 is 180 - 45 =135.
