What are two adjacent angles that measure 180?
If the angles are EACH 180 degrees and they are placed adjacent, then they forma complete revolution of 360 degrees.If the two angles add up to 180 degrees when they are placed adjacent, then they aresupplementary angles.
Adjacent angles add up to be 90 degrees?
No. Complementary angles add up to 90 degrees. Supplementary angles add up to 180 degrees.
What term describes two adjacent angles whose measures add up to 180?
They are said to be supplementary angles that add up to 180 degrees
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).
Two angles whose sum equals 180 degrees?
Are said to be supplementary.
