A square is a rectangle, rectangles don't have to be squares but squares have to be rectangles.
A rhombus is a quadrilateral whose four sides are congruent. Squares are a type of rhombus with congruent angles. Since there are 4 contruent angles, they must all be right angles.So any quadrilateral that is equilateral is a rhombus and any rhombus with 4 right angles is a square. Every rhombus is a parallelogram because the opposite angles of a rhombus are congruent. Also, the diagonals of a rhombus are perpendicular.
Square, retangle
You can make a retangle and diamond. :)
It is: 7*8 = 56 square inches
40 square units
In some cases, a rectangle and a square can be congruent. A square is counted as a rectangle, thus a rectangle can be congruent to a square.
Because it depends on how big the retangle/square is.
No. If you made a parallelogram with congruent sides it wouldn't necessarily have congruent angles. A square has to have congruent angles as well as congruent sides.
All sides of a square are congruent.
You have to multiply the two dimensions to get the area. In this case the answer will be 600 square feet.
