Supplementary angles are two angles that add up to 180 degrees. Complimentary angles are two angles add up to 90 degrees.
Kinda hard here to graph the angles, but:
(1) Draw a 90 degree angle: The angle of any line drawn for the apex is a complemetary angle to the other.
(2) Draw a straight line (180 deg): The angle of any line that meets the straight line is a supplementary angle to the other.

What are some examples of complementary angles?
ANY two angles that total 90o, eg the "other" angles in a right-angled triangle.
The supplementary angle of a 45 degree angle has how many degrees?
Angles are supplementary if they add up to 180. So, with some algebra 45+x=180 x=180-45=135
What angles have measures that add up to 90 degrees?
The Answer:30, and 60, or 37, 33, 20 are some examples. These angles are considered "complementary angles". There are 56634173 partitions (with integer values and including 90 itself) for 90.
Does some parallelograms have 4 right angles?
Yes a rectangle for example
Do quadrilaterals have right angles?
"Quadrilateral" simply means "four sided". Some quadrilaterals do have right angles; squares or rectangles, for example. Some have one or two right angles, but some don't have any right (90 degree) angles.
