Quadrilateral Shapes and Facts. A quadrilateral is a polygon with 4 edges, corners, and interior angles. 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.
Important Facts of Quadrilateral. A quadrilateral is a trapezoid or a trapezium if 2 of its sides are parallel to each other. A quadrilateral is a parallelogram if 2 pairs of sides parallel to each other. Squares and Rectangles are special types of parallelograms. Below are some special properties.
Square, rectangle, rhombus, and trapezoid are examples of a convex quadrilateral. b) Concave Quadrilateral. It is a type of quadrilateral with at least one of its interior angles measuring greater than 180°. A concave quadrilateral has one of its diagonals outside the closed figure. Dart or arrowhead is an example of concave quadrilateral.
Complex Quadrilaterals. Oh Yes! when two sides cross over, we call it a "Complex" or "Self-Intersecting" quadrilateral, like these: They still have 4 sides, but two sides cross over. Polygon. A quadrilateral is a polygon. In fact it is a 4-sided polygon, just like a triangle is a 3-sided polygon, a pentagon is a 5-sided polygon, and so on.

Solved Examples on Quadrilateral. Example 1. Find the missing angle in the given quadrilateral. Solution: We know that the sum of all the angles of a quadrilateral is 360°. Hence, we can write it as follows: x + 77° + 101° + 67 = 360°. x + 245° = 360°. x = 360° – 245°.
A quadrilateral is a closed shape that is formed by joining four points among which any three points are non-collinear. In simple words, a quadrilateral is a polygon with 4 sides, 4 angles, and 4 vertices. Let us learn more about the quadrilateral shape, the properties of quadrilaterals, the different types of quadrilaterals along with a few ...
Area of quadrilaterals. The area of a quadrilateral is just the measurement of the region that’s enclosed by its sides. There are different formulas you have to use for each type of quadrilateral: Rectangle — b x h. Square — x 2. Trapezoid — b x h. Parallelogram — b x h. Kite — ½ x d 1 x d 2. Rhombus — ½ x (a + b) x h.
A quadrilateral is a polygon with four sides or edges and four vertices or corners. Quadrilaterals include trapezoids, rhombuses, rectangles, and squares. Quadrilaterals may be classified according to number of pairs of parallel sides: ) One Pair of Parallel Sides () No Parallel Sides. Related Topics:

A. The perimeter of a quadrilateral can be found by adding the lengths of all the four sides of a quadrilateral. Test your knowledge: Learn about 7 types of Quadrilaterals based on definition and properties • Parallelogram • Square • Rectangle • Rhombus • Kite • Trapezium • Irregular.
A quadrilateral is a type of polygon. Side– A side is a straight line or straight boundary of two dimensional polygons. Vertex: A vertex is a point where two lines of a polygon meet or intersect. Angle: Where two sides of a quadrilateral meet, an angle is formed. It is formed when two different sides have a common point.
The perimeter of a square is 4 times the length of one side. Quadrilaterals with 2 sets of parallel side are called parallelograms. A rhombus is a quadrilateral with four sides of the same length. A diamond shape is a good example of a rhombus. A convex (outward) quadrilateral with one pair of parallel sides is known as a trapezoid in the US ...
Answer: 1 – d, 2 – b, 3 – c, 4 – a, 5 – b, 6 – a, 7 – d. Quadrilaterals are 2D shapes that are a type polygon with 4 sides and 4 angles. QUAD means four, LATERALS means side. The sum of all interior angles is 360 degrees.
Therefore a quadrilateral is a closed two-dimensional polygon made up of 4-line segments. In simple words, a quadrilateral is a shape with four sides. Quadrilaterals are everywhere! From the books, chart papers, computer keys, television, and mobile screens. The list of real-world examples of quadrilaterals is endless. Types of Quadrilaterals

A rhombus is a type of quadrilateral shape where all four sides are of equal length. They also have two pairs of parallel sides, and opposite angles are equal in size. If diagonal lines are drawn from opposite corners, they will meet in the middle of the shape at right-angles. You can often see rhombuses called diamonds or rhombus!
