obtuse angle
The 3 interior angles of any triangle add up to 180 degrees
Interior angles add up to 180 degrees Exterior angles add up to 360 degrees
supplementary angles add up to 180 degrees
no. the angles in a triangle must add up to 180 degrees. The right triangles must have an right angle (90 degrees). If you add up all the angles they will not measure 180 degrees.
they add up to 180 degrees
A triangles angles have to add up to 180 degrees so since there are two angles that measure 40 it is 180-80=100(answer.)
Supplementary angles add up to 180 degrees
The 3 interior angles of any triangle add up to 180 degrees.
Supplementary angles.
Supplementary angles are two angles that measure up to 180 degrees. EXAMPLE: If the an angle measures 70 degrees, to find the missing angle, you subtract 70 from 180 because supplementary angles equal 180 degrees. Your answer (in this case 110) is the answer for the measure of the missing angle.
Supplementary angles add up to 180 degrees
Supplementary angles are two angles that add up to 180 degrees. In other words, if you have one angle measuring x degrees, its supplementary angle will measure 180 - x degrees.
