What if two angles are equal and supplementary are the angles obtuse acute or right angles?
They both will be right angles that add up to supplementary angles 180 degrees
If uncommon arms of two adjacent angles are collinear then these angles are called?
Supplementary
If a parallelogram has one right angle then all of its angles must be right?
Yes. This is true because opposite angles are congruent and adjacent angles are supplementary.
Angles that add up to 90 degrees are called?
Complementary angles. Angles that add up to 180 are called supplementary angles. :)
What is the difference between complementary and supplementary angles?
Complementary angles add up to one right angle (90 degrees), such as 30 degrees and 60 degrees. Supplementary angles add up to a straight angle, which is 2 right angles (180 degrees). So the supplement of a 30 degree angle is 150 degrees. For any given angle, its supplement is 90 degrees greater than its complement.
