What else can I help you with?
If a quadrilateral is a square then it is a parallelogram. A quadrilateral is a square if and only if it is a parallelogram.?
The second statement is false.
The opposite angles of a quadrilateral in a circumscribed circle are always complementary?
false
If a quadrilateral is a parallelogram and the diagonals are perpendicular then is it a square?
By that description, all the sides are parallel and have 90 degree angles... But the sides aren't necessarily the same length. So a square is one example, but you could also have a long rectangle. apex=False
Opposite sides are parallel true or false?
it depends on its shape. if it is a parallelogram, then its true. but if it is a trapezoid, then eventually not.
Is a rhombus not always a parallelogram?
False. A rhombus is always a parallelogram.
True or False- If opposite angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
false
If opposite angles of a quadrilateral are supplementary is the quadrilateral a parallelogram?
No. A quadrilateral is a parallelogram when consecutiveangles are supplementary.
True or false the diagonals of a quadrilateral must bisect each other and be perpendicular to guarantee that the quadrilateral is a parallelogram?
False. Bisecting diagonals is sufficient to guarantee a parallelogram, but the diagonals will only be perpendicular if the sides of the parallelogram are equal.
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 this statement true or falseProving that the diagonals of a quadrilateral are perpendicular will show that a quadrilateral is a parallelogram?
false
The diagonals of a quadrilateral must bisect each other and be perpendicular to guarantee that the quadrilateral is a parallelogram?
False
The diagonals of a quadrilateral must bisect each other and be perpendicular to guarantee that the quadrilateral is a parallelogram.?
false
A parallelogram is a quadrilateral in which opposite sides are perpendicular?
A parallelogram doesn't necessarily have any perpendicular sides, but it can. If it has one single 90-degree angle, then it has four of them, and it's a rectangle. Apexvs geometry 2nd sem -- false.
True or false If opposite angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
True
If a quadrilateral is a parallelogram and the diagonals are perpendicular then it must be a square?
False. It could be a rhombus.
If two opposite sides of a quadrilateral are parallel and congruent then the quadrilateral is a parallelogram?
False
If a quadrilateral is a parallelogram and the diagonals are perpendicular then it must be a rectangle?
False. ^^^ Wronnngg! Its True (Apex). ^ No you are wrong, It is false.
