You have an 8-foot ladder. The safety instructions say the base of the ladder must be 3 feet away from the side of the building. How far up the building can the ladder reach?
length of ladder = hypotenuse
distance from building = leg #1
distance up the building = leg #2

Bricklayers use the fact that a 3-4-5 triangle is a right triangle (which is a consequence of the Theorem of Pythagoras) to lay out right angles.

Pythagoras theorm can be used in the following ways:- 1)determining the trajectory of a bullet or the distance from something you are 2)Walls were erected using the Pythagorean theorem. 3)a squared + b squared = C squared 4)it can be used to find distances on maps from one place to another using the grids on the map and then convert the map scale to see how far apart they actually are on the ground. It is actually pretty cool. I never thought I'd use the pythagoran theorem for anything!

an engineer only equipped with a transit and a leveling rod has to determine the height of a building just a few meters from him, could he be able to do the job?
yes he could. with the aid of his transit and rod he could determine the distance of the building with respect to the transit as well as the angle with respect to the horizontal position of the transit by spotting from the transit the top of the building. and given the angle and the horizontal distance the height can be now determine using the Pythagoras theorem.

Very important in laying out the foundation for a new building. It is important to have all angles exactly equal to 90 degrees. The building being rectangular, or having rectangular sections, you would be able to calculate the required diagonals using the Pythagorean Theorem.

You are deserted in northern iraq, the road runs north for 30 miles, turns at 90 degrees, then runs a further 15 miles to get to the next city. However at the start point, there is, a car, and.....A HELICOPTER!!!
How far is it to the next city, as the crow flies?

a man is on one side of a river/ . He can not just simply cross it
He want tp know the distance between two points on the opposite side of the river.
This is the problem.
Wjat is his method used to solve the problem using only the tape and calculator.
