Introduction
3D shapes look different from different directions (top, front & side)
Pre-Requisites:
Plane Shapes, Solid Shapes
Activity:
Go for an irregular building & try to study how it appears from different views. This is the best way for you to master visualization
Real Life Question:
How does a multistory building with inclined roof look from different directions?, Why does a building which is 3D look like a rectangle from the front?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Front View | Go to the front of the object & see which 2D shape it is in |
| Side View | Go to the side of the object & see which 2D shape it is in. It may be same or different from various sides |
| Top View | Imagine U r flying up in the sky & hence, look at the object from there and conclude which 2D shape it is in |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| A thin book | Look at its shape. From the, Top = Square, Either side = A line, Front = Square |
Real life uses :
To design a ship, it need to be studied in detail from every view because different parts are located in different places
Places to visit :
Any amusement park, Museum
Practical examples around us
| Examples | Explainations |
|---|---|
| A chair | From the front, it looks like a hemisphere on the top of a square. From either side, it looks like a stepped building |
What you learn in Theory:
How to view 3D objects as 2D objects
What you learn in Practice:
All of the objects around us which are mostly 3D look like different or same 2D objects when viewed from different directions
