1. Pythagores Theorem Application

2. Introduction
The Pythagorean Theorem is one of the most useful formulas in mathematics because there are so many applications of it in out in the world.
Some examples:
architects and engineers use this formula extensively when building ramps
Painting on a Wall
Crossing the pond in shortest way
Constructing a tent

3. Question #1
To get from point A to point B you must avoid walking through a pond.  To avoid the pond, you must walk 34 meters south and 41 meters east.  To the nearest meter, how many meters would be saved if it were possible to walk through the pond? 
solution
The given question is illustrated in the figure. Given AC=34m,CB=41m.
To find AB
We know that by Pythagorean theorem.

4. Question #2
Oscar's dog house is shaped like a tent.  The slanted sides are both 5 feet long and the bottom of the house is 6 feet across.  What is the height of his dog house, in feet, at its tallest point?
Solution
From the diagram,
AB=AC=5,BC=6.
To Find AD
In ∆ADC, by Pythagorean theorem.

5. Question #3
Solution
How far up a wall will an 11m ladder reach, if the foot of the ladder must be 4m from the base of the wall?
From the diagram,
This figure has been restructured as ∆ABC
Given AC=11m, BC=4m
To find AB
by Pythagorean theorem.

6. Try These
A 24 m long ladder reached a window 25m high from the ground. On placing it against a wall at a distance x m. Find x.
A rectangular field is of dimension 40m by 30m. What distance is saved by walking diagonally across the field?
