If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is not a parallelogram?
False. If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is a parallelogram.
Is each interior angle of a quadrilateral always 90 degrees?
No. in a rhombus the angles are not 90 degrees. also in a parallelogram they are not 90 degrees
If one pair of opposite angles of a quadrilateral are congruent and one pair of opposite angles are congruent then is the quadrilateral a parallelogram?
For the quadrilateral to be a parallelogram, both pairs of opposite angles must be congruent.
If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is a parallelogram?
True
True or false If opposite angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
True
If a quadrilateral is a parallelogram then consecutive angles are complementary?
Consecutive angles in a parallelogram will not be complementary. Complementary would mean the angles would add up to 90 degrees. Consecutive angles add up to 180 degrees, meaning they are supplementary.
Are complementary angles consecutive angles in a parallelogram?
The question does not really make sense. Once might ask, "Are consecutive angles in a parallelogram complementary?" in which case the answer is no. Complementary angles are angles which add up to 90 degrees. Consecutive angles are angles next to each other (or follow each other). In a parallelogram, consecutive angles are supplementary (add to 180 degrees). In a parallelogram, opposite angles are equal. You could have a parallelogram where two angles are 45 degree (and thus complementary) and then the other two angles would be 135 degrees.
Is a quadrilateral with Consecutive angles are complementary?
It is an impossible quadrilateral since its angles would not sum to 360 degrees but only 180 degrees.
Is it true or false that in a parallelogram the opposite angles are complementary?
Generally false. In a parallelogram, the opposite angles are equal. They could be complementary in a highly skewed parallelogram in which one angle is 45 degrees.
Why does a parallelogram equal 360 degrees?
The interior angles of all quadrilaterals sum to 360 degrees. Since a parallelogram is a quadrilateral, its interior angles must sum to 360 degrees.
Why aren't adjacent angles in a parallelogram complementary?
That would give you a sum total of 180 degrees for all 4 angles inside the parallelogram, but it needs to be 360 degrees.
What are angles of parallelograms?
The angles of a parallelogram can vary but the interior angles will always add up to 360 degrees, as it is a quadrilateral.
What quadrilateral has 2 angles of 75 degrees and 105 degrees and has 2 pairs of congruent sides?
A parallelogram.
What quadrilateral has sides that are parallel and has angles are not 90 degrees?
Any parallelogram that is not also a rectangle.
If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is not a parallelogram?
False. If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is a parallelogram.
How many angles and sides in parallelogram?
A parallelogram is a quadrilateral which has 4 sides and 4 interior angles that add up to 360 degrees
Does a parallelogram have a 90 degree angle?
No , a parallelogram can not have a 90 Degree angle .Reason : A Parallelogram can be defined as a quadrilateral whose two s sides are parallel to each other and all the four angles at the vertices are not 90 degrees or right angles, then the quadrilateral is called a parallelogram.
