List four things that have the shape of a parallelogram,and list the differences between a parallelogram and a rectangle,and list the similarities between a parallelogram and a rectangle
Four things that have the shape of a parallelogram:
1. A book.
2. A street sign.
3. A playing card.
4. A computer screen.
Differences between a parallelogram and a rectangle:
1. A rectangle has four right angles, while a parallelogram does not necessarily have any right angles.
2. In a rectangle, all four sides are equal in length, while in a parallelogram, opposite sides are equal in length.
3. A rectangle is a special type of parallelogram where all angles are right angles, while a parallelogram can have any angle measurements.
4. The diagonals of a rectangle are of equal length and bisect each other, while the diagonals of a parallelogram are of unequal length and do not necessarily bisect each other.
Similarities between a parallelogram and a rectangle:
1. Both have four sides.
2. Both have opposite sides that are parallel to each other.
3. Both have opposite angles that are equal.
4. Both have diagonals that divide the shape into two congruent triangles.
