![]() ![]() In the case of a square (where all four sides are equal in length), the equation becomes: C= 4s. The circumference (C) of a parallelogram (or the distance around it) is denoted: C= 2b+ 2H. It may seem that way, but technically, a sphere is a 3-D shape (has width, height, and depth) and a circle is 2-D (width and height) A circle is missing the depth needed to become a 3-D shape. A diagonal of a quadrilat- eral is a line segment whose end-points are opposite vertices of the quadrilateral. Since all four sides (s) of a square are equal, then b= h= s, and its equation can be written A= 2s. What are 4 sided shapes called quadrilateral Definition: A quadrilateral is a polygon with 4 sides. The area (A) of a parallelogram is equal to the distance (length) of one side, called its base b, times the shortest distance (length) to the opposite side, called its altitude or height h. A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel (marked with arrows below): is an isosceles trapezoid when it has equal angles from a parallel side. That is, all four sides are equal in length and the sides that contain a common point are at right angles to one another. The computer screen you are looking at right now is probably in the shape of. Three special types of parallelograms are called the rhombus, the rectangle, and the square.Ī rhombus is a parallelogram with all four sides of equal length but the sides to not necessarily meet at right angles to one another.Ī rectangle is a parallelogram whose adjacent sides are perpendicular (meet at right angles) to one another and opposite sides are equal in length.Ī square is a parallelogram whose adjacent sides are both perpendicular (angled at 90 °) and equal in length. A quadrilateral is a four-sided polygon, like a square, rectangle, or rhombus. (A diagonal is a line that joins two opposite corners of a geometric figure, such as a parallelogram.) In all types of parallelograms, the diagonals cut each other in half (or, bisect each other) where they intersect.

This four-sided figure is called a polygon (a two-dimensional figure formed of three or more straight sides) or, more specifically, a quadrilateral (a 2D figure formed of four straight sides). A parallelogram, in plane geometry, is a plane figure of four sides whose opposite sides are parallel to each other and where each side is equal in length to its opposite side. ![]()
