Not clear what exactly the question is.
a linear pair!
The angle formed by the noncommon sides of two adjacent and supplementary angles is called a linear pair. Supplementary angles are two angles whose measures add up to 180 degrees, and when they are adjacent, they share a common vertex and one side. The noncommon sides of these angles extend in opposite directions, creating a straight angle measuring 180 degrees.
Two adjacent angles that have noncommon sides forming a line are called supplementary angles. This means that the two angles add up to 180 degrees. The noncommon sides of the angles create a straight line, demonstrating their supplementary relationship. An example of this would be a pair of angles that share a vertex and one side, with their other sides extending in opposite directions to form a straight line.
If the noncommon sides of two adjacent angles form a right angle, then the angles are complementary angles.
A right angle.
A pair of adjacent angles whose non-common sides are opposite rays are called a linear pair. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Right Angle! (:
-- Opposite sides are parallel. -- Opposite sides are equal. -- All four sides are equal. -- Adjacent sides are equal. -- Adjacent angles are supplementary. -- Opposite angles are equal. -- Diagonals are perpendicular. -- Interior angles sum to two straight angles. -- Exterior angles sum to two straight angles.
One pair of equal angles can be found in an isosceles triangle, where the angles opposite the equal sides are congruent. For the equal adjacent sides, consider a rectangle, where each pair of adjacent sides (length and width) is equal to the corresponding sides on the opposite side. Thus, in a rectangle, we have two pairs of equal adjacent sides, while the opposite angles are also equal.
square and a rectangle
A quadrilateral with 4 right angles and opposite sides that are parallel can be either a rectangle if the adjacent sides are of different length or a square if the adjacent sides are of the same length.
Yes, two adjacent angles whose exterior sides are opposite rays are complementary. This is because the angles formed by the opposite rays sum up to 180 degrees, and since they are adjacent, their measures add up to 90 degrees, fulfilling the definition of complementary angles. Thus, the two angles are indeed complementary.
