These quadrilaterals are called parallelograms They take a variety of shapes, but one classic example is shown below. A rectangle is a parallelogram that has all four angles equal to 90°. And you have four right angles. All internal angles are of “right angle” (90 degrees).– Each figure contains 4 right angles.– Sides of a square are of the same length (all sides are congruent) – Opposite sides of a rectangle are same.– Opposite sides of a rectangle and square are parallel. A rhombus is a type of parallelogram, and what distinguishes its shape is that all four of its sides are congruent.. Menu. Make at least one conjecture about the diagonals of rectangles.

Thus a rectangle or a rhombus, or any 4 sided shape that does not have all four sides the same length AND all angles 90 degrees. A rectangle also has the special characteristic that all of its angles are right angles; all four of its angles are congruent. If you know what the quadrilaterals look like, their definitions should make sense and be pretty easy to understand (though the kite definition is a bit of a mouthful). All sides are congruent.
