In a parallelogram consecutive angles are always?
In a parallelogram consecutive angles are always supplementary. This means they equal 180.
If a quadrilateral is a parallelogram then its consecutive angles are?
Then it's consecutive angles are supplementary.
Which quadrilaterals have supplementary consecutive angles?
An equilateral quadrilateral which would include a square.
What is a parallelogram with one interior angle equal to 90?
It is a square, a regular parallelogram with all right angles. The reason is that in a parallelogram, the adjacent angles are supplementary (equal 180 degrees).In any case, the opposite angle would be 90 degrees as well, leaving just 180 degrees for the other two identical opposite angles.
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 adjacent angles in a parallelogram are supplementary?
Adjacent angles in a parallelogram are supplementary.
If opposite angles of a quadrilateral are supplementary is the quadrilateral a parallelogram?
No. A quadrilateral is a parallelogram when consecutiveangles are supplementary.
In a parallelogram the consecutive angles are?
Supplementary.
Consecutive angles in a parallelogram are?
supplementary
Are the angles of a parallelogram supplementary?
Yes
Are opposite angles in a parallelogram supplementary?
No, they are equal. Adjacent angles are supplementary in a prallelogram.
Parallelogram consecutive angles conjecture?
supplementary
Are the consecutive angles of a parallelogram supplementary?
yes
Why consecutive angles of a parallelogram are supplementary?
Basa
Are consecutive angles in a parallelogram always congruent?
Not unless the parallelogram is a rectangle. In every parallelogram, consecutive angles are supplementary.
What quadrilateral has 2 pairs of supplementary angles?
A parallelogram.
What are the nonadjacent angles in a parallelogram. Supplementary or congruent?
congruent
