A rectangle.
Well, honey, that's not a parallelogram, that's a rectangle. A parallelogram can have opposite sides equal in length and opposite angles equal in measure, but not necessarily right angles. So, in this case, you're describing a rectangle, not a parallelogram. But hey, at least you're on the right track!
A square.
parallelogram
sometime actually -A rectangle is a parallelogram with 4 right angles. -A square is a parallelogram with 4 right angles and 4 congruent sides. Congruent sides are the same length.
All rectangles have 4 sides. All parallelograms have 4 sides. A rectangle is a parallelogram with all 4 angles of 90°
When all 4 corners are right angles. A parallelogram has two pairs of parallel sides. A rectangle has two pairs of parallel sides; therefore a rectangle is a parallelogram. A rectangle also has four 90° angles; a parallelogram does not necessarily have four 90° angles, therefore a parallelogram may, or may not, be a rectangle.
A rectangle.
It is a rectangle
A parallelogram is only a rectangle if it has 4 right angles. A square is a rectangle, but not vice versa because a square has all equal side lengths, four sides, AND four right angles. A rectangle has four right angles and 4 sides.

A square.
A parallelogram with four right angles is a rectangle; if the rectangle also has four equal sides, then it is known as a square.
parallelogram
It is a rectangle.
Every parallelogram has 4 sides.If it has 4 right angles, then it's a rectangle.(Actually, a parallelogram with one right angle must be a rectangle.)
It's a rectangle. A rectangle has four right angles, but only two pairs of equal sides.
