Question

What are the properties of

2 D

shapes

?

Accepted Answer

There are no fixed properties of the 2D shape. As each shape have a different number of sides and for each shape, properties vary. But, every 2D shape is flat and is enclosed.

A two-dimensional (2D) shape has two dimensions that we can measure: we can measure the length, and we can measure the breadth (sometimes called the width) of the shape. For example, a square is a 2D shape. All the sides of a square are straight lines. A circle is also a 2D shape, but a circle has a curved edge.

$2 D Shapes$ $Properties$

Circle Circles having equal radii are said to be congruent.
The diameter of a circle is the longest chord of the circle.
The perpendicular drawn on any given chord of a circle from the canter of the circle bisects the chord into two equal halves.
All chords of a circle equidistant from the canter of the circle are equal in length.

Triangle The sum of all three internal angles of a triangle is $180 °, i . e . ∠ A + ∠ B + ∠ C = 180 ° .$
The sum of all three external angles of a triangle is $360 °, i . e . ∠ A ’ + ∠ B ’ + ∠ C ’ = 360 ° .$
The measure of an external angle of a triangle is equal to the sum of the measures of the two internal opposite angles.
4. The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Square A square is a quadrilateral with four equal sides and four equal internal angles.
It is a rhombus with four equal angles (each angle equals 90°).
A square is a rectangle with its two adjacent sides equal.
It is a parallelogram with all four internal angles equal to 90° and adjacent sides equal in length.

Rectangle A rectangle is a quadrilateral with four equal internal angles.
Each internal angle of a rectangle measures 90°.
As the opposite angles of a rectangle are equal, a rectangle is also a parallelogram.
The opposite sides of a rectangle are equal and parallel

Pentagon The sum of interior angle is 540 degree.
It is a regular pentagon, if all the sides and angles are equal.
It consists of five side and angles.
