What shape has 4 sides and 4 points?
- Tangential quadrilateral: the four sides are tangents to an inscribed circle. ...
- Tangential trapezoid: a trapezoid where the four sides are tangents to an inscribed circle.
- Cyclic quadrilateral: the four vertices lie on a circumscribed circle. ...
- Right kite: a kite with two opposite right angles. ...
How many degrees are there in a 4 sided shape?
The sum of the degrees of the angles of a polygon equals 180 (n-2), where n equals the number of sides of the polygon. A rectangle has four sides, so the sum of its angles is equal to 180 (4-2), or 360 degrees. A pentagon has five sides, so the sum of its angles is equal to 180 (5-2), or 540 degrees.
What are facts about 4 sided shapes?
- A quadrilateral is a polygon with 4 sides and 4 corners.
- The word ‘quadrilateral’ comes from ‘quad’ meaning ‘4’ and ‘lateral’ meaning ‘of sides’.
- The interior angles of quadrilaterals add to 360 degrees.
- Any quadrilateral with 4 right angles is a rectangle.
- A quadrilateral with 4 right angles and 4 equal length sides is a square. ...
What shape has 4 equal sides and 4 corners?
Properties of Various Two-Dimensional Shapes are as follows. It has four sides and four corners. A square could be a quadrilateral with four equal sides and 4 equal internal angles. A square could be a parallelogram with 2 adjacent sides equal. It is a quadrangle with all four internal angles adequate to 90° and adjacent sides equal long.
What is the name of all 4 sided 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 is a 4 sided irregular shape called?
An irregular four sided shape is called an irregular quadrilateral. An irregular quadrilateral differs from a regular one because not all of its sides are equal in length.

What are irregular shapes called?
An irregular polygon does not have all its sides equal and not all the angles are equal in measure. Examples of irregular polygons are scalene triangle, right triangle, isosceles triangle, rectangle, parallelogram, irregular pentagon, irregular hexagon, etc.
What are the irregular shapes?
Irregular shapes are polygons with five or more sides of varying lengths. These shapes or figures can be decomposed further into triangles, squares, and quadrilaterals to evaluate the area. Apply this technique for the shapes with curves apart from perfect circle or semicircles and irregular quadrilaterals.
How do you find the area of a 4 sided irregular shape?
To find the area of such irregular quadrilaterals, follow a three-step strategy: Divide the quadrilateral into two triangles by constructing a diagonal that does not disturb the known interior angle. Calculate the area of each triangle, using formulas. Add the areas of the two triangles.
What is an irregular polygon?
An irregular polygon is a 2D shape that has straight sides that are not equal to each other and angles that are not equal to each other.
Rectangles and Squares
There is a reason why rectangles and squares are put in the same section. They are very much like each other. In fact, one is exactly like the other. So what is a rectangle?
Rhombuses and Parallelograms
Parallelograms and rhombuses have the same relationship with each other that rectangles and squares do. What is a parallelogram? A parallelogram is a quadrilateral that is similar to a rectangle but has some slight differences. A parallelogram has the following special attributes:
Kites
It might be hard to answer the question of whether the chicken or the egg came first, but it is easy to answer which came first between the toy flying kite or the shape. The kite is a type of quadrilateral that gets its name from the traditional shape of the kite that flies on a string. The reason for the name is simple; the shape is the same.
How many sides does a quadrilateral have?
It has two pairs of sides: Each pair is made of two equal-length sides that join up. Also: the angles where the two pairs meet are equal. the diagonals, shown as dashed lines above, meet at a right angle. one of the diagonals bisects (cuts equally in half) the other. ... and that's it for the special quadrilaterals.
What are the different types of quadrilaterals?
Types of Quadrilaterals. There are special types of quadrilateral: Some types are also included in the definition of other types! For example a square, rhombus and rectangle are also parallelograms. See below for more details.
What is a parallelogram?
A parallelogram has opposite sides parallel and equal in length. Also opposite angles are equal (angles "A" are the same, and angles "B" are the same). NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!
What is a rectangle?
A rectangle is a four-sided shape where every angle is a right angle (90°).
Is a quadrilateral a square?
The only regular (all sides equal and all angles equal) quadrilateral is a square. So all other quadrilaterals are irregular.
Where do diagonals meet?
Another interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. In other words they "bisect" (cut in half) each other at right angles.
Which trapezoid has left and right sides of equal length that join to the base at equal angles?
An Isosceles trapezoid, as shown above, has left and right sides of equal length that join to the base at equal angles.
