what are always supplementary angles?
607197
Sum it up: Supplementary angles are two angles whose sum is 180°. A linear pair (two angles that form a line) will always be supplementary. The two angles can be adjacent or non-adjacent.

Yes opposite angles of a trapezoid are supplementary. Supplementary angles of a trapezoid is defined as the sum of two opposite angles is 180...

Opposite Angles Theorem. ... In a cyclic quadrilateral, opposite angles are supplementary. If a pair of angles are supplementary, that means they add up to 180 degrees. So if you have any quadrilateral inscribed in a circle, you can use that to help you figure out the angle measures.

© 2015 MathsIsFun.com v 0.82. When the two angles add to 180°, we say they "Supplement" each other. Supplement comes from Latin supplere, to complete or "supply" what is needed.

Two angles are said to be complementary when the sum of the two angles is 90°. ... Corresponding angles are congruent. All angles that have the same position with regards to the parallel lines and the transversal are corresponding pairs e.g. 3 + 7, 4 + 8 and 2 + 6.

Alternate angles form a 'Z' shape and are sometimes called 'Z angles'. a and b are adjacent angles. Adjacent angles add up to 180 degrees. ... d and f are interior angles. These add up to 180 degrees (e and c are also interior).

The Theorem The consecutive interior angles theorem states that when the two lines are parallel, then the consecutive interior angles are supplementary to each other. Supplementary means that the two angles add up to 180 degrees.

A Parallelogram is a flat shape with opposite sides parallel and equal in length. Angles "a" and "b" add up to 180°, so they are supplementary angles.

Prove that any two adjacent angles of a parallelogram are supplementary. Then, AD ∥ BC and AB is a transversal. ... Thus, the sum of any two adjacent angles of a parallelogram is 180°. Hence, any two adjacent angles of a parallelogram are supplementary.

Complementary angles are those angles whose sum is equal to 90o. Thus, complementary angles are always acute angles. Hence, two acute angles can be complementary.
1079044
Yes, adjacent angles can be complementary. Complementary angles are defined as two acute angles with a sum that is equal to 90°.

So, what have you learned? You learned that complementary angles are two angles that add up to 90 degrees, supplementary angles are two angles that add up to 180 degrees, vertical angles are opposite angles at an intersection of two straight lines, and adjacent angles are two angles that are next to each other.

The sum of angles in a rhombus is 360°. Opposite angles are equal to each other and adjacent angles are supplementary angles.

Supplementary Angles are two angles the sum of whose measures is 180º. Supplementary angles can be placed so they form a linear pair (straight line), or they may be two separate angles.
958481
Supplementary angles are two angles whose sum is 180 degrees while complementary angles are two angles whose sum is 90 degrees. Supplementary and complementary angles do not have to be adjacent (sharing a vertex and side, or next to), but they can be. ... And I noted here that these do not have to be adjacent.

One of the basic properties of parallelograms is that any pair of consecutive angles are supplementary. We'll prove this property using one of the theorems about parallel lines – the Consecutive Interior Angles Theorem. ...

Theorem:Vertical angles are always congruent. In the figure, ∠1≅∠3 and ∠2≅∠4. Proof: ∠1and∠2 form a linear pair, so by the Supplement Postulate, they are supplementary.
