Answer:
In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers.
Irrational numbers:
In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers.
A real number that can NOT be made by dividing two integers (an integer has no fractional part). "Irrational" means "no ratio", so it isn't a rational number. ... Example: π (the famous number "pi") is an irrational number, as it can not be made by dividing two integers.
Trapezium:
In Euclidean geometry, a convex quadrilateral with at least one pair of parallel sides is referred to as a trapezium in English outside North America, but as a trapezoid in American and Canadian English.
Area: ½ x (sum of the lengths of the parallel sides) x perpendicular distance between parallel sides
Perimeter: sum of lengths of sides of trapezoid
Number of vertices: 4
Number of edges: 4
Properties: Convex polygon
Type: Quadrilateral
Line of symmetry: 0
Rhombus:
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. ... A rhombus with right angles is a square.
Area: ½ x (product of the lengths of the diagonals)
Perimeter: 4 x side
Number of vertices: 4
Number of edges: 4
Properties: Isotoxal figure, Convex polygon
Type: Parallelogram, Quadrilateral, Kite
Line of symmetry: 2
