No. Complementary angles add up to 90 degrees.

Supplementary angles add up to 180 degrees.

Sketch the two adjacent angles 90 degrees and 90 degrees This is an example of angles?

Adjacent angles are two angles that are next to each other and share one side (ray) in common. They do not have to add up to 180 degrees, but they can. If the two of them add up to 180 degrees, they are called a linear pair, since their non-common sides will be opposite rays that make a straight line. Two 90-degree angles that are adjacent are a linear pair. They are supplementary (meaning they add up to 180 degrees) and a sketch of them will look like a T, either upside-down (typical), sideways, or right-side up, depending on how you want to draw them.


Are all angles of a parallelogram equal to 90 degrees?

No, only in a square (regular parallelogram).The opposite angles are EQUAL in a parallelogram, and the adjacent angles are SUPPLEMENTARY(they equal 180 degrees).So if any angle in a parallelogram is a right angle, they all are. Otherwise, there are no right angles.The angles of a parallelogram will average 90 degrees, as there are 360 degrees in any quadrilateral, (360/4 - 90) and 180 degrees in two adjacent non-equal angles (180/2 = 90).


Are all complementary angles adjacent?

No, because a complamentary angle just equals 90 degrees. An adjacent angle has a vertex and a common ray the same. If you have two angles that are not touching they cannot be adjacent because they dont have a same ray, but they may have a same vertex. If the two angles add up to 90 degrees they are complimentary and dont have to have anything the same. Hope this helps! If it is confusing look up what an adjacent angle is, then look up what a complamentary angle is! :)


What shape has angles that add up to 360 degrees?

Square 90.______90. |. | |. | 90.______ 90.


Two angles that fit together to form a right angle?

Those angles are called complimentary angles. They add up to 90 degrees. Two angles that add up to 180 degrees are called supplementary angles.
