are adjacent angles of a quadrilateral supplementary?
312839
All sides are congruent. Opposite angles are congruent. The diagonals are perpendicular to and bisect each other. Adjacent angles are supplementary (For eg., ∠A + ∠B = 180°).

The opposite sides of a parallelogram are equal (and conversely: if the opposite sides of a quadrilateral are equal, it is a parallelogram). The opposite angles of a parallelogram are equal (and conversely: if the opposite angles of a quadrilateral are equal, it is a parallelogram).

Supplementary angles are two angles whose sum is equal to \begin{align*}180^\circ\end{align*}. In other words when you add the measure of one angle in the pair with the other angle in the pair, they equal 180 degrees.

The measures of the adjacent angles of a parallelogram add up to be 180 degrees, or they 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.

A linear pair is by definition supplementary, but two supplementary angles are only a linear pair if they are also adjacent.

Theorem 47: If both pairs of opposite angles of a quadrilateral are equal, then it is a parallelogram. ... Theorem 49: If one pair of opposite sides of a quadrilateral is both equal and parallel, then it is a parallelogram. Theorem 50: If the diagonals of a quadrilateral bisect each other, then it is a parallelogram.

It is a quadrilateral with two pairs of parallel, congruent sides. Its four interior angles add to 360° and any two adjacent angles are supplementary, meaning they add to 180° . Opposite (non-adjacent) angles are congruent. The two diagonals of a parallelogram bisect each other.

Two adjacent angles can be complementary too, if they add upto 90°. For example, a diagonal of a square will split the right angle into two equal angles; 45°+45°.

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.

Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°). If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other.

Two angles are said to be supplementary when the sum of the two angles is 180°. ... 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.

Adjacent Angles are two angles that share a common vertex, a common side, and no common interior points. ... If two angles form a linear pair, the angles are supplementary. A linear pair forms a straight angle which contains 180º, so you have 2 angles whose measures add to 180, which means they are supplementary.

Because of the parallel sides, consecutive angles are same-side interior angles and are thus supplementary. (All the special quadrilaterals except the kite, by the way, contain consecutive supplementary angles.) Reason for statement 1: Given. Reason for statement 2: The legs of an isosceles trapezoid are congruent.

There are some special relationships between "pairs" of angles. Adjacent Angles are two angles that share a common vertex, a common side, and no common interior points. (They share a vertex and side, but do not overlap.) ∠1 and ∠2 are adjacent angles.

Corollary 4: Two consecutive angles in a rhombus are supplementary and opposite sides are parallel. Proof: By considering , we see that Now, the measure of angle BDC is and the measure of angle DCA is so the sum of these two consecutive angles is 180 degrees; thus, they are supplementary.

No, because if two consecutive angles are supplementary, then another pair of consecutive angles are also supplementary. Since a kite has one pair of congruent opposite angles, then two pairs of opposite angles must be congruent.

Answer and Explanation: Yes, adjacent angles can be complementary. Complementary angles are defined as two acute angles with a sum that is equal to 90°. Thus, any two...
