Not necessarily. All parallelograms are quadrilaterals but not all quadrilaterals are parallelograms. Parallelograms are more specific instances of quadrilaterals. Its like saying all squares are rectangles but not all rectangles are squares.
Yes, a parallelogram has four sides, making it a quadrilateral. All parallelograms are quadrilaterals, but not all quadrilaterals are parallelograms.
A parallelogram belongs to the family of quadrilaterals because it has 4 sides.
No. A parallelogram is a special kind of quadrilateral.
A shape that is a parallelogram but not a quadrilateral doesn't exist.
It's not a matter of 'finding' it. Either the quadrilateral is a parallelogram,or else it is not one.If the opposite sides of the quadrilateral are parallel, then it's a parallelogram.
The second statement is false.
A quadrilateral is a parallelogram if it has two pairs of (opposite) sides that are parallel.
A parallelogram must have 4 sides and so it must be a quadrilateral. However, the sides of a quadrilateral need not be parallel so a quadrilateral need not be a parallelogram.
A quadrilateral is a polygon with four sides. A parallelogram is a quadrilateral in which the opposite sides are parallel.
No. A parallelogram is a special kind of quadrilateral.
A shape that is a parallelogram but not a quadrilateral doesn't exist.
In this case, the quadrilateral is sometimes a parallelogram.
No. A quadrilateral is a parallelogram when consecutiveangles are supplementary.
No, a parallelogram is not another kind of quadrilateral.
It's not a matter of 'finding' it. Either the quadrilateral is a parallelogram,or else it is not one.If the opposite sides of the quadrilateral are parallel, then it's a parallelogram.
Square, Quadrilateral, and Parallelogram.
A quadrilateral is a parallelogram if it has two pairs of (opposite) sides that are parallel.
The second statement is false.
Theorem A: A quadrilateral is a parallelogram if its opposite sides are congruent. Theorem B: A quadrilateral is a parallelogram if a pair of opposite sides is parallel and congruent. Theorem C: A quadrilateral is a parallelogram if its diagonals bisect each other. Theorem D: A quadrilateral is a parallelogram if both pairs of opposite angles are congruent.
