all the angles are right angles (90 degrees) and add to 360 degrees
A trapezoid, if the angles going around the shape are 90, 90, 120, 60.
Two angles that add up to 90 degrees are called complementary angles.
Two angles whose measures add to 90 are complementary angles. An example is 45 and 45.
The angles are complimentary when they add to 90 degrees.
The 4 interior angles of the square will add up to 360 degrees
well right angle is 90 degress or a perfect l a straight angle is 180 degress
Complementary angles add to 90 degrees.
Complementary angles are when the angle measures of the two angles add up to 90.
90 degress :P
They are complementary angles that add up to 90 degrees
