A complementary angle is one of two angles that together equal 90 degrees. For example, if one angle is 30 degrees, its complementary angle would be 60 degrees, because together they add up exactly to 90.

Can I see some Example of supplementary and complementary angles?

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.
