Two-Dimensional Shapes
(1) Line Segment
A part of line.
(2) Curve
A smooth line representing some mathematical function.
(3) Circle
The path of a point remaining at same distance from a fixed point.
(4) Arc
A part of a circle. Here, red portion is the arc below.
(5) Triangle
A closed figure bounded by three lines.
(6) Quadrilateral
A closed figure bounded by four line segments.
Following are main types of quadrilaterals.
A) Square
Quadrilateral with all sides equal.
B) Rectangle
Quadrilateral with opposite pair of sides equal.
C) Rhombus
All sides equal and opposite side parallel.
D) Parallelogram
Opposite sides equal and parallel.
E) Trapezium
One pair of opposite sides is parallel.
(6) Polygon
A closed figure having at least three sides. Triangles, quadrilaterals, pentagon, hexagon etc are included in this class.
Three-Dimensional Shapes
(1) Cube
A shape surrounded by 4 congruent squares.
(2) Cuboid
A box having 6 rectangular faces. Opposite faces are congruent to each other.
(3) Cylinder
A hollow or solid shape circular or oval base and straight sides that are parallel.
(4) Cone
A hollow or solid shape tapering from a circular base to a point outside the base.
(5) Sphere
A 3d form of circle.
(6) Pyramid
A shape with triangular or quadrilateral shaped based and slant sides meeting in a point outside the base. A rectangular pyramid is shown below :
(7) Prism
A solid shape with two base that are congruent geometric figures. The bases are joined together with parallel lines or parallelograms faces. A triangular prism is demonstrated below:
