A square is always a rectangle

A rectangle is never a rhombus

A rhombus is sometimes a square

A rhombus is always a parallelogram

A trapezoid never has three congruent sides

The diagonals of a trapezoid never bisect each other

The diagonals of a rectangle are never congruent

The diagonals of a parallelogram sometimes bisect the angles


-any of deez wrong?

yeah, the last one. it should be spelt 'these'.

regardless, a square is never a rectangle, since a square has to have sides of equal length.

triangles can have sides of equal length, but a square has to have two sides that are parallel.

i didn't say anything about triangles...

besides, i always classed rectangles as 2 sets of parallell lines, where the X is different from the Y. that would include rhombus'

2 and 7 are wrong.

btw i always hated math, especially geometry, so you decide if you should listen to me or not.

A trapezoid has two lines parallel.
A parallelogram has two sets of parallel lines.
A rhombus is a parallelogram with equal sides.
A rectangle is a parallelogram with right angles.
A square is a rectangle with equal sides (alternately, a rhombus with right angles).

I think 5, 6, and 7 may be wrong. The others are all definitely correct.

IndieMetalhead and Biatch, a square is a rectangle. It is a special one, with all sides equal.

BodaciousZac and ar73m, a rectangle is never a rhombus because a rhombus must have all sides equal.

Threadstarter, I am afraid that up til now you have been mislead.

*Looks very satisfied with self*.


Edit: The guy above me was correct.

^ Correct. EVERY square is a rectangle, since the only requirement for a rectangle is that all angles are 90 degrees and opposite sides are equal. In a square, every angle is 90 degrees and opposite sides are equal, it just happens that all sides are equal. By the same rationale, every square and rectangle is a parallelogram.

5. A trapezoid can have three congruent sides. For three sides to be congruent, the fourth would also have to be, and opposite sides would be parallel and opposite angles would be equal. Enter the rhombus, which is a very special type of trapezoid.

6. They can bisect each other - if it's a special trapezoid, the parallelogram (which includes, rectangles, rhumbuses and therefore squares as well).

7. The diagonals of a rectangle are always congruent (equal).
