The Square. the little squares in each corner mean "right angle". A square has equal sides (marked "s") and every angle is a right angle (90°) Also opposite sides are parallel. A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length).
The rhombus has a square as a special case, and is a special case of a kite and parallelogram. In plane Euclidean geometry, a rhombus (pl.: rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length.
The opposite sides are parallel, meaning the square has two pairs of parallel sides. The parallel sides are annotated with matching arrowhead(s) in the same direction. The angles are all right angles.
Show step. Shape A A: 4 4 equal angles (right angles), each pair of opposite sides are equal in length, 2 2 pairs of parallel sides. Shape B B: One pair of equal angles (right angles), one pair of parallel sides. Shape C C: 4 4 equal angles (right angles), 4 4 equal sides, 2 2 pairs of parallel sides. Shape D D: 4 4 equal angles (right angles ...

- A rectangle is just a shape that has four right (90 degree) angles and four sides where opposite sides are parallel. There’s also a special type of...
Feb 7, 2011 · The area of a trapezium is equal to the product of the length of the median line by the height of the trapezium, or to half the product of the diagonals by the sine of the angle between them. A trapezium whose lateral sides are equal is called equilateral. Figure: t094020a. In the English literature, a trapezium is also called a trapezoid.

Jul 18, 2023 · The main shapes are square, rectangle, rhombus, kite, parallelogram, and trapezoid. In geometry, a quadrilateral is a two-dimensional closed shape or polygon that has four straight sides, four corners or vertices, and four interior angles. The sum of the interior angles is 360 degrees. The word “quadrilateral” comes from the Latin words ...
