What is a rectangle polygon?
Rectangle Definition For a shape to be a rectangle, it must be a four-sided polygon with two pairs of parallel, congruent sides and four interior angles of 90° each. If you have a shape that matches that description, it also is all this: A plane figure. A closed shape. A quadrilateral.
What is a rectangle simple definition?
A rectangle is a 2D shape in geometry, having 4 sides and 4 corners. Its two sides meet at right angles. Thus, a rectangle has 4 angles, each measuring 90 ̊. The opposite sides of a rectangle have the same lengths and are parallel.
What is properties of rectangle?
What is the difference between rectangle and polygon?
A regular polygon must be both equilateral (all sides are the same length) and equiangular (all angles of the same measure). A rectangle is equiangular. All of its sides equal 90˚ by definition. However, a rectangle can never, by definition, be equilateral.
Why is it called a rectangle?
The word rectangle comes from the Latin rectangulus, which is a combination of rectus (as an adjective, right, proper) and angulus (angle).
What is the definition of polygon in geometry?
polygon, In geometry, any closed curve consisting of a set of line segments (sides) connected such that no two segments cross. The simplest polygons are triangles (three sides), quadrilaterals (four sides), and pentagons (five sides).
What are types of rectangles?
What is rectangle and its type?
A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.
How do you know if a polygon is a rectangle?
A regular polygon must be both equilateral (all sides are the same length) and equiangular (all angles of the same measure). A rectangle is equiangular. All of its sides equal 90˚ by definition.
What is difference square and rectangle?
The major difference between square and rectangle is that a square has all its sides equal whereas a rectangle has its opposite sides equal. In Geometry, we have learnt different types of shapes such as square, rectangle, cube, cone, cylinder, parallelogram, rhombus, and so on.
Is a rectangle a polygon shape?
A polygon is any shape made up of straight lines that can be drawn on a flat surface, like a piece of paper. Such shapes include squares, rectangles, triangles and pentagons but not circles or any other shape that includes a curve.
