Introduction about two dimensional shape:

A two-dimensional shape is known as the “regular" each of its faces is the similar length and each of its angles is the similar angle. Two dimensional shapes is also known as the plane surface or plane figure, and the line fragments or faces and the arcs all are placed in the same plane. The arc and face are called as the edges of the shape.

Two- Dimensional Shapes( Names)

The edges of the 1 dimensional shapes are placed in the plane are called as the two dimensional shape. These edges of the end points are called as either corners or vertices. Those points are called as 0-dimensional but they are placed in the plane so it is called the two dimensional.

Above shapes are known as plane shapes and shapes has the two dimensions they are length and width.

Brief Notes for Two Dimensional Shapes:

Square:

In square opposite faces are similar and each side has the same length. Square each angle is equal into 90 degree. In square all sides’ lengths are equal.

Triangle:

Triangle is the virtual types of geometry. It is a polygon which has the 3 vertices and three faces and those are line segments are known as triangle. Triangle is the two- dimensional shape with 3 side plane.

Parallelogram:

Parallelogram is one type of the quadrilaterals. Parallelogram opposite sides is parallel and equal in length. Parallelograms opposite angles are equal. Parallelogram has the equal contradictory faces and angles and the contradictory faces are similar properties of a parallelogram

Rhombus:

Rhombus has the equal length in all of its sides. Opposite sides are equal in parallelogram. And the diagonals angles are equal. Parallelogram diagonals are intersects at right angles.

Trapezium:

Any one pair of equal sides is parallel in the trapezium. If non-parallel pair of opposite sides is equal and it is called as isosceles trapezium. In isosceles trapezium it has the non- parallel faces and equal, the base angles of the trapezium is also equal.

Octagon:

A regular polygon which consists of 8 sides with equal length and same dimension of the internal angles is known as octagon. For more details refer Geometry World
