Is quadrilateral Q a square?
(1) The sides of Q have the same length.
(2) The diagonals of Q have the same length
In a parallelogram, not all the sides have the same length from what I understand.
Or am I missing something?
Parallelogram CAN have all 4 sides of equal length.
Parallelogram A quadrilateral with two pairs of parallel sides.Properties and Tips• Opposite sides of a parallelogram are equal in length.
• Opposite angles of a parallelogram are equal in measure.• Opposite sides of a parallelogram will never intersect.
• The diagonals of a parallelogram bisect each other.• Consecutive angles are supplementary, add to 180°.•
The area, \(A\), of a parallelogram is \(A = bh\), where \(b\) is the base of the parallelogram and \(h\) is its height.
• The area of a parallelogram is twice the area of a triangle created by one of its diagonals.
A parallelogram is a quadrilateral with opposite sides parallel and congruent. It is the "parent" of some other quadrilaterals, which are obtained by adding restrictions of various kinds:• A rectangle is a parallelogram but with all angles fixed at 90°
• A rhombus is a parallelogram but with all sides equal in length
• A square is a parallelogram but with all sides equal in length and all angles fixed at 90°
