- Plane Hallway: A plane is A smooth flat surface which extends infinitely on all four sides.
- Vertex: the point where two lines meet to form an angle is called a vertex.
- Parallel walls: lines on a plane that do not intersect at any point and are of equal length are parallel lines.
- Line Segment: The shortest path which connects any two points on a plane is called a line segment.
- Perpendicular lines: two lines that intersect at right angles are perpendicular lines.
- Line: A straight path formed by a collection of infinite dots and extends endlessly on either direction is a line.
- pointing finger: A point has only position but no length, breath and thickness.
- Polygon: A polygon is a shape which is made out of straight lines.
- Intersecting Lines: Two or more lines that meet at a point are intersecting lines.
- Closed Curve: The curves that begin and end at the same point are called closed curves
- Quadrilaterals: A polygon with four sides is a quadrilateral
- Sun's bursting out rays: A ray has a starting point but no end point, it extends infinitely.
