rhombus
if only 2 sides are parallel but 2 others are not, then it is a trapezoid (trapezium)
A trapezoid is a quadrangle with one pair of parallel sides.
That's a kind of trapezoid.
A rhombus.
A parallelogram has two sets of parallel sides. It can have four sides that are equal in length. That is why a square is also a parallelogram. You can have a parallelogram with two sets of parallel sides, all of which are equal in length, but they do not meet in right angles. It looks kind of like a lopsided or squished square, and it is called a rhombus.
The shape that fits this description is a parallelogram. A parallelogram has two pairs of parallel sides, meaning that opposite sides are parallel. Additionally, a parallelogram does not have any right angles, as the sum of its adjacent angles is always 180 degrees. Examples of parallelograms include rectangles, squares, rhombuses, and rectangles.
A rectangle is a special kind of quadrilateral that has four right angles and opposite sides that are equal and parallel.
A rectangle is a special kind of quadrilateral that has four right angles and opposite sides that are equal and parallel.
a square as it is the only parallelogram with all four sides of equal length and all four angles are right angles
An invisible quadrangle!
corresponding and alternate angles
The three types of trapeziums (or trapezoids in American English) are: Isosceles trapezium: This has a pair of parallel sides and the non-parallel sides are equal in length, with base angles that are also equal. Right trapezium: This features one pair of parallel sides and has one angle that is a right angle (90 degrees). Scalene trapezium: This has a pair of parallel sides but the non-parallel sides are of different lengths and angles are not equal.
Either they are parallel to or they intersect each other.
