In any triangle ABC ,

If we know the three sides of any triangle, we can find the angles of the triangles using this formula.


Example:


In a triangle ABC, given a=25, b=52, c=63. Find A

Solutions of Triangle

published on September 20th, 2006 . by Vanaja

I think yesterday you had a big laugh after reading math genius. So today we are fresh and can have some lessons from Trigonometry.

We know the three sides and three angles of a triangle are called its parts. The process of finding the unknown parts of a triangle from its known parts is known as solution of a triangle. This has many applications in surveying, navigation, astronomy and other sciences.
In a Triangle ABC, The angles are denoted by A,B,C and the lengths of the corresponding opposite sides BC, CA and AB by a,b, and c respectively.

The Law of Sines


Using this formula we can find solutions of a triangle.If any three parts are given, we can find the other three parts.

The Magic Triangle?

published on September 18th, 2006 . by Vanaja

See the picture below

Can you tell me the answer?

It’s an optical illusion.The hypotenuse of both triangles seem to be straight lines but they’re not.
I think the answer lies in the fact that neither shape is actually a triangle, they are quadrilaterals. They have four sides.

The side that looks like it is the hypotenuse is actually two sides, the corner being where the green and red triangle.
I have searched the web and find an answer here.

If you have any good explanation about this please let me know.

10 Trees Problem

published on September 12th, 2006 . by Vanaja

There are 10 trees spaced out equally along my street with one at each end. If I run at a steady speed from one end of the street, I can reach the 5 th tree in just 5 seconds.

How long would it take me to run down the whole street at the same pase?
( No, it is not 10 seconds)





Did you get the answer?

When I reach the 5 th tree I cover 4 trees.
So,time taken to cover 4 trees is 5 seconds.
So, time taken to cover 1 tree is 5/4 seconds.
When I reach the 10 th tree I cover 9 trees.
So, time taken to cover 9 trees( and this is same as the time taken to run down the whole street) is 9 multiplies 5/4
ie 45/4
or
11.25 seconds
