Volume and Surface Area | Geometrical Relationship ?

Saturday, April 19th, 2008

Using geometry, we can determine the volume and surface area of any object. However, have you wondered what is the relationship between them? If we want to maintain the volume of an box but reduce its surface area, is it possible? Or does the volume ALWAYS increases with increase in its surface area? How ...

Who Says The Compass Triangle Is Right-Angled?

Friday, April 11th, 2008

A simple way to obtain a right-angled triangle is to draw a triangle with its corners touching the edge of a circle with its diameter as one side of the triangle. Look at this post  for details on what I am talking (or rather writing) about. However,  the question is how do we know ...

How To Draw Right-Angled Triangle Using Geometric Compass

Wednesday, April 9th, 2008

We can draw a right-angled triangle using various ways. One way is to make use of a protractor. Another way is to use a try square. But what if you have only a geometric compass, how do you do it? (Not the compass that give you directional bearings of north, south, east and west! It ...

Exciting Area and Perimeter in Geometry

Tuesday, April 8th, 2008

In geometry studies, you would come across, definitely, the terms "area" and "perimeter". I suppose, you are also good at calculating their numerical value. However, in the midst of doing the many calculations and heavily involved with different funny shapes, the fundamentals of geometry have to be maintained. The principles are always ...

Why Is Net Important In Geometry?

Tuesday, April 8th, 2008

Geometry does involve objects in the 3-D perspective. The height factor of the geometrical outlook is presented in the 3-dimensional view. But does it really present the object with a complete understanding of its shape? There may be assumptions made if the angle of view is not appropriate. The assumptions may be wrong! Let me ...

Pyramid - An Ancient Shape

Thursday, March 27th, 2008

Geometry has lasted a long time ago. The Egyptian Pyramids of Giza in Egypt is a famous example. What is so special about the shape of this pyramid? It differs from other shape in that, besides the base, all its other surfaces end up in a vertex, or pointed tip at one end. Actually this ...
