These identifying open and closed shapes worksheets pdfs are recommended for 1st grade and 2nd grade children. Sorting 2D Shapes. Composing and Decomposing 2D Shapes. Identifying and Naming 2D Shapes. Our identifying open and closed shapes worksheets make learning enjoyable, through exercises that teach to differentiate shapes as open or closed.
Examples of a quadrilateral are square, rectangle, rhombus, parallelogram, trapezium, etc. A pentagon is a closed shape with 5 sides and 5 vertices. A hexagon is a closed shape with 6 sides and 6 vertices. There are many other closed shapes in geometry apart from the ones that are mentioned above, for example, heptagon, octagon, decagon, oval, etc.
Polygons are closed figures made of straight lines without intersections. The sides of regular polygons are all the same length. In these worksheets, students identify polygons and regular polygons. Polygons: Worksheet #1. Regular polygons: Worksheet #2. Worksheet #3. Similar:

In geometry, the definition of a polygonis given as a closed two-dimensional figure which is formed by three or more straight lines. The properties of polygons help us identify them easily. In other words, the following characteristics of a polygon help us to easily check whether a given shape is a polygon or not 1. A polygon is a closed shape, tha...
The sides of a polygon define the name of the specific polygon because different polygons have different number of sides. For example, if a polygon has 3 sides, then it is called a triangle, whereas, if a polygon has 4 sides, it is a quadrilateral. The following section shows the different types of polygons along with their names based on the numbe...
There are different types of polygons and they have different names depending on the number of sides that they have. For example, a 3-sided polygon is a triangle, a 4-sided polygon is a quadrilateral, a 5-sided polygon is a pentagon, a 6-sided polygon is a hexagon, and so on.
The following chart shows the naming convention of polygons on the basis of the number of sides that they have. Each polygon is given a special name on the basis of its number of sides. For example, the trigon, also known as the triangle is made of two words 'tri' which means three, and 'gon' means angles. This shows that it is a shape that has thr...
It is said that as per Euclidean Geometry, a polygon that is equiangular and equilateral is called a regular polygon while a polygon whose sides are not equiangular and equilateral is referred to as an irregular polygon. Regular polygons are always convex,i.e., all the interior angles measure less than 180º. In simple words, a regular polygon has a...
The interior angles are formed between the adjacent sides inside the polygon and are equal to each other in the case of a regular polygon. The number of interior anglesis equal to the number of sides. The value of an interior angle of a regular polygon can be calculated if the number of sides of the regular polygon is known by using the following f...
Each exterior angle of a regular polygon is formed by extending one side of the polygon (either clockwise or anticlockwise) and then the angle between that extension and the adjacent side is measured. Each exterior angle of a regular polygonis equal and the sum of the exterior angles of a polygon is 360°. An exterior angle can be calculated if the ...
The area of a polygon is defined as the measurement of space enclosed within a polygon. The area of polygons can be found by different formulas depending upon whether the polygon is a regular or an irregular polygon. For example, a triangle is a three-sided polygon which is known as a trigon. The formula for calculating the area of the trigon (tria...
The perimeter of a polygon is defined as the distance around a polygon which can be obtained by summing up the length of all given sides. The perimeter of polygon formula = Length of Side 1 + Length of Side 2 + Length of Side 3...+ Length of side N (for an N-sided polygon). It is expressed in terms of units such as meters, cm, feet, etc. Concave po...

A circle is a closed shape with one face and no sides or vertices. A quadrilateral is a four-sided closed shape having four vertices. Square, rectangle, rhombus, parallelogram, and trapezium are some examples of quadrilaterals. A pentagon is a five-sided closed shape with five vertices. There are many more closed shapes in geometry than the ...

Supplies needed: small piece of cardboard or paper, scissors, graph paper. Directions: Label the four sides of the graph paper with the words up, down, left, right. Cut a small object out of the cardboard. Place it on the graph paper and trace it. Now move it over in a straight line, and then up or down.
