Introduction
It’s quite easy to visualize in in 2D that how to get distance between two points by simply applying Pythagoras theorem, but the task becomes quite difficult in 3D as you have to visualize everything in mind or have to draw 3D diagrams.
Pre-Requisites:
2D Cartesian plane, Plotting of points in 2D, 2D coordinate geometry.
Activity:
2D Cartesian plane
Real Life Question:
null
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Three dimensional space | Three-dimensional space is a geometric 3-parameters model of the physical universe in which we exist. |
| Cartesian coordinate system | A Cartesian coordinate system specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances from the point to two fixed perpendicular directed lines, measured in the same unit of length. |
