Why is a square also a rectangle?
Because there opposite sides are congruent. And all squares are rectangles, but not all rectangles are squares!
What is a 3 dimensional figure that has three pairs of opposite parallel congruent faces that are rectangles?
This depends on if the question is asking for each pair of opposite rectangles must be congruent, then it is a rectangular prism.If all of the rectangles are congruent, then it must be a Cube. A square is a special case of a rectangle, and all 6 sides being squares makes a cube and they are all congruent.
Why are all rectangles parallelograms?
because that is how rectangles are defined. that's like asking why are all circles round-_-;;because the opposite sides are congruent (same).
Are all rectangles perpendicular?
Yes. The basic definition for a rectangle is 4 sides, four right angles(perpendicular), and opposite sides are congruent.
Are rectangles opposite angles congruent?
Yes.
What is a quadrilateral with opposite sides of congruent?
Parallelograms, rhombuses, squares, and rectangles are the quadrilaterals that have opposite congruent sides.
Is it true that rectangles have no sides are congruent?
No because opposite sides of a rectangle are congruent and parallel
Do all rectangles have 4 congrent sides?
No. Usually only opposite sides are congruent.
Why is a square also a rectangle?
Because there opposite sides are congruent. And all squares are rectangles, but not all rectangles are squares!
Why Can all rectangles be cut in half vertically or horizontally to make to congruent rectangles?
They make two congruent rectangles, not to rectangles! This is because the line joining the midpoints of opposite sides are lines of [reflective] symmetry.
What quadrilaterals have opposite sides congruent?
Slanted polygons, rectangles, squares, trapazoids, kites
Does a rectangle have all congruent sides?
No, rectangles do not have congruent sides. Squares have congruent sides.
Do all rectangles have four congruent sides?
No, only those rectangles that are squares have four congruent sides.
Are Squares the same as Rectanangles?
No. Squares technically qualify as rectangles (parallel opposite sides, ninety degree angles, opposite sides are congruent, etc.) however rectangles do not qualify as squares. Squares MUST have four sides of equivalent length, and rectangles do not meet this criterion.
What quadrilateral has opposite sides that are congruent?
That would be a parallelogram. (Rectangles, Squares and Rhombuses are special types of parallelograms.)
What is a 3 dimensional figure that has three pairs of opposite parallel congruent faces that are rectangles?
This depends on if the question is asking for each pair of opposite rectangles must be congruent, then it is a rectangular prism.If all of the rectangles are congruent, then it must be a Cube. A square is a special case of a rectangle, and all 6 sides being squares makes a cube and they are all congruent.
