Why rectangles and rhombuses are also parallelograms?
Well, A Rectangle is a parallelogram because there are 4 sets of lines that are parallel :) I dont know about the rhombus sorry :(! ~ A rhombus is only a parallelogram if: 1. It is a regular rhombus (where all the sides are the same length and there are 2 sets of parallel sides) 2. There is at least one pair of parallel sides.
What quadrilaterals have at least one pair of parallel sides?
A trapezoid (or trapezium) has at least one pair of parallel sides.If you asked, "Name all the types of quadrilaterals which have at least one pair of parallel sides?", I would answer: Trapezoid, rhombus, parallelogram, rectangle and square.
Do all quadrilaterals have at least one pair of parallel lines?
No.
Is rectangle a rhombus and parallelogram?
It is a parallelogram, but a square is all three. all four of them (rectangle; rhombus; parallelogram; square) are quadrilaterals. all five are polygons. a quadrilateral is any shape with four sides. a rectangle is any shape with all right angles. a parallelogram has two pairs of parallel( non-intersecting lines). a rhombus is a parallelogram with congruent (same) sides. polygons are any closed shape with strait lines. a trapezoid has only one pair of parallel lines. a trapizoid also is a quadrilateral and a polygon, but none of the others.
Do a rhombus have 2 right angles 1 pair of parallel sides and no sides are the same?
We're starting with a rhombus.-- 2 right anglesNot necessarily. A rhombus doesn't need any right angles in order to be a rhombus,but it can have some, and if it has one right angle, then it has four of them.-- 1 pair of parallel sidesA rhombus has two pairs of parallel sides. If it doesn't, then it's not a rhombus.-- no sides are the sameIf it's a rhombus then all four of its sides are the same length. If they're not, then it isn't a rhombus.
