Square. Opposite sides are parallel and all sides are equal.
Parallelogram. Opposite sides are parallel and equal.
Rhombus. All sides are equal and opposite sides are parallel.
Trapezium. A trapezium has one pair of opposite sides parallel.
What is a quadrilateral and its types?
Answer: A quadrilateral refers to a four-sided polygon that has four angles. The seven types of quadrilaterals are parallelogram, rhombus, kite, rectangle, trapezoid, square, and isosceles trapezoid. Answer: A trapezoid refers to a 4-sided flat shape with straight sides and it has a pair of parallel opposite sides.
What are the quadrilateral shapes?
A quadrilateral is a four-sided two-dimensional shape. The following 2D shapes are all quadrilaterals: square, rectangle, rhombus, trapezium, parallelogram and kite.
What are 4 types of quadrilaterals?
There are 5 types of quadrilaterals – Rectangle, Square, Parallelogram, Trapezium or Trapezoid, and Rhombus.
What are the 4 types of parallelograms?
The four basic properties of parallelogram are: Opposite sides of a parallelogram are equal. Opposite angles of parallelogram are equal. Diagonals divide the parallelogram into two congruent triangles.
There are three special types of parallelogram, they are:
Is a kite always a quadrilateral?
A kite is a quadrilateral (four sided shape) where the four sides can be grouped into two pairs of adjacent (next to/connected) sides that are equal length. A square is a rhombus is a kite is a quadrilateral. A kite is not always a rhombus.
What are special Quadrilaterals?
Special quadrilaterals: Information sheet
A trapezium is a quadrilateral with one pair of sides parallel. A kite is a quadrilateral with two pairs of adjacent sides equal. A parallelogram is a quadrilateral whose opposite sides are parallel. A rhombus is a quadrilateral with all sides equal.
What is the correct name for a quadrilateral?
Parallelogram is the proper name of the quadrilateral. This answer has been confirmed as correct and helpful.
What is quadrilateral explain with diagram?
In geometry, a quadrilateral can be defined as a closed, two-dimensional shape which has four straight sides. The polygon has four vertices or corners. We can find the shape of quadrilaterals in various things around us, like in a chess board, a deck of cards, a kite, a tub of popcorn, a sign board and in an arrow.
What is formula of quadrilateral?
The interior angles add up to 360 degrees. Also, for some quadrilaterals, the opposite sides are parallel and opposite angles are equal.

What is area of quadrilateral?
If the diagonal and the length of the perpendiculars from the vertices are given, then the area of the quadrilateral is calculated as: Area of quadrilateral = (½) × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices.
What is the area of quadrilateral ABCD?
We know that the perimeter of the quadrilateral = the sum of all the sides of the quadrilateral ABCD = (AB + BC + CD + DA). We have all the values for the sides, so we get the perimeter as, = (8 + 5 + 13 + 10) cm = 36 cm. So, we have got the area of the quadrilateral as 69.7cm2 and the perimeter as 36 cm.
How do you find the area of a convex quadrilateral?
Observing first the convex quadrilaterals we can see that the area of a convex quadrilateral can be expressed as the sum of the two areas divided by any of the diagonals, A(ABCD)=A(ABC)+A(CDA)=A(BCD)+A(DAB).
How do you find the area of a special quadrilateral?
How do you find the area of a irregular quadrilateral?
The area of any irregular quadrilateral can be calculated by dividing it into triangles. Example: Find the area of a quadrilateral ABCD whose sides are 9 m, 40 m, 28 m and 15 m respectively and the angle between the first two sides is a right angle. The area of the quadrilateral ABCD =(180+126)=306 square meters.
How do you find the perimeter and area of a quadrilateral?
What is the formula of perimeter of quadrilateral?
The formula is a + b + c+ d = perimeter. For example, suppose that a quadrilateral has sides with lengths of 1, 5, 3 and 4 inches. The perimeter equals 1 + 5 + 3 + 4 or 13 inches.
Is Triangle a quadrilateral?
A triangle is a simple closed curve or polygon which is created by three line-segments. On the other hand, in terms of Euclidean plane geometry, a polygon having four edges (or sides) together with four vertices is called a quadrilateral.
Is a parallelogram a quadrilateral?
Parallelograms are quadrilaterals with two sets of parallel sides.
