2d Shapes

2d Shapes 2D is the geometric shapes which has length and breadth and which can be represented on a xy plane. Since it has length and breadth, therefore it is known as 2 D or two dimensional figure. Few examples of 2D: - Triangle Quadrilateral Circle Triangle: - A triangle is a plane closed figure bounded by three line segments. It has three sides, three angles and three vertices. Types of triangle: - Equilateral triangle: - i) All sides are equal. ii) Each angle of it is 60 degree. Isosceles triangle: - i) Two sides are equal and ii) Two angles are equal. Scalene triangle: - i) All three sides are unequal Acute- angled triangle: - i) One of the angle is less than 90 degree. Obtuse- angled triangle: - i) One of the angle is more than 90 degree. Right- angled triangle:- i) One of the angle is equal to 90 degree. Quadrilateral: - A quadrilateral is a plane closed figure bounded by four line segments. It has four sides, four angles and four vertices. Types of quadrilateral: - Square: - i) All sides are equal and ii) Each angle of it is 90 degree. Rhombus: - i) All sides are equal and ii) Opposite angle are equal. Rectangle: - i) The opposite sides are equal and ii) Each angle of it is 90 degree. Parallelogram: - i) The opposite sides are equal and ii) Opposite angle are equal. Circle: - A circle is another (different) type of plane figure which is not bounded by line segment.
