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 every quadrilateral is a rectangle true or false?
False. Not every quadrilateral is a rectangle; a rectangle is a specific type of quadrilateral that has four right angles and opposite sides that are equal in length. There are many other types of quadrilaterals, such as squares, rhombuses, trapezoids, and irregular quadrilaterals, which do not meet the criteria of a rectangle.
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.
