Question

properties of all 2D shapes ​

Answer 1

Answer:

2D Shapes Names:

1. Circle
2. Triangle
3. Square
4. Rectangle
5. Pentagon
6. Octagon

Circle:

A circle is a closed 2d figure in which the set of all the points in the plane is equidistant from a given point called “center”. The distance from the center to the outer line of the circle is called a radius. The example of the circle in real life are wheels, pizzas, orbit, etc.

Triangle:

A triangle is a three-sided polygon (2d Shape) which has three edges and three vertices. The sum of all the three angles of a triangle is equal to 180°. Pyramids are the best example of a triangle shape.

Square:

A square is a four-sided polygon (2d Shape), whose four sides are equal in length and all the angles are equal to 90°. It is considered to be a two-dimensional regular quadrilateral. The diagonals of the square also bisect each other at 90°. A wall or a table where all the sides are equal are the examples of square shape.

Rectangle:

A rectangle is a 2d shape which has four sides, where the opposite sides are equal and parallel to each other. All the angles of a rectangle are equal to 90°. A brick, TV, cardboard, which has length and breadth are examples of the rectangle.

Pentagon:

A pentagon is a five-sided polygon (2d Shape), and it can be regular or irregular. In the case of a regular pentagon, each interior angle is equal to 108°, and each exterior angle measures 72°. It has five diagonals. The Pentagon building, which is the headquarters of the US Department of Defense, is a great example of the pentagon shape.

Octagon:

An octagon is an eight-sided polygon which can be either regular or irregular. It is a 2d shape which has eight angles. The sum of all the interior angles of an octagon is 1080°. The stop sign board has an octagon shape, which you can see on the roadside.

Properties of 2D shapes are:

Square:

Four equal sides

Four equal angles (90°)

Four axes of symmetry

Rectangle:

2 sets of 2 equal sides

Four equal angles(90°)

Two axes of symmetry

Triangle:

It can have no, 2 or 3 equal sides

It can have no, 2 or 3 equal angles

Usually no axes of symmetry

Circle:

Constant diameter and radius

The total angle of a circle is equal to 360 degrees

Almost infinite axes of symmetry going through the centre

Pentagon:

5 sides (can be equal or unequal)

5 angles (can be equal or unequal)

It can have up to 5 axes of symmetry

Hexagon:

6 sides (can be equal or unequal)

6 angles (can be equal or unequal)

It can have up to 6 axes of symmetry
