Rhombus

Image
  In plane   Euclidean geometry , a   rhombus   (plural   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 rhombus is often called a   diamond , after the   diamonds   suit in   playing cards   which resembles the projection of an   octahedral   diamond , or a   lozenge , though the former sometimes refers specifically to a rhombus with a 60° angle (which some authors call a   calisson   after   the French sweet [1]   – also see   Polyiamond ), and the latter sometimes refers specifically to a rhombus with a 45° angle.

  Learn Practice Download Parallelogram The term ‘parallelogram’ was derived from the Greek word ‘parallelogrammon’ which stands for “bounded by parallel lines”. Hence, a parallelogram is a quadrilateral that is bounded by parallel lines. It is a shape in which the opposite sides are parallel and equal. Parallelograms are classified into three main types: square, rectangle, and rhombus, and each of them has its own unique properties. In this section, we will learn about a parallelogram, how to find the area of a parallelogram and other aspects related to a parallelogram along with the solved examples. What is a Parallelogram? A parallelogram is a special kind of   quadrilateral   that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram. A quadrilateral will be a parallelogram if its opposite sides are parallel and congruent. Hence, a parallelogram is defined a...

LCM

  Least Common Multiple Calculator Find the LCM of a set of numbers with this calculator which also shows the steps and how to do the work. Input the numbers you want to find the LCM for. You can use commas or spaces to separate your numbers. But do not use commas within your numbers. For example, enter  2500, 1000  and not  2,500, 1,000 .
