Who Was Pythagoras?
What Was Pythagoras Remembered For?
When Was Pythagoras Born? When Did He Die? When Did He Discover The Pythagorean Theorem?
Where Was Pythagoras Born? Where Did He Discover The Pythagorean Theorem? Where Did He Visit To Get His Ideas?
Where In The World Would Someone Use Right Triangles And The Pythagorean Theorem?
They are:
- Construction: Use a special triangle (or a multiple of it, say, 9-12-15) when they don't have a carpenter's square (instrument for constructing right angles) handy
- Farming: Precise lines need to be drawn and measured to determine growing spaces and yearly yield a tool is vital
- Painting: Painter needs to be able to determine how tall the ladder needs to be in order to safely place the base away from the wall so it won't tip over
- Road Trips: Need to be able to calculate the shortest possible way to your destination
- Welders: These people use the Pythagorean Theorem when they are welding objects together to make right triangles, and they could possibly may also need to know the hypotenuse of the object they are welding
- Cartographers: These people use the Pythagorean Theorem when setting boundaries, for example, they can easily measure a line
Steps To Making The Wheel Of Pythagoras?
Collect materials - one poster board, one pencil, and one ruler with centimeters on it
Step 2:
Measure 27.5 cm from the left of the poster board and 20.5 cm from the top of the poster board and make a mark, this would be our center of the wheel
Step 3:
We will make a segment. This segment needs to be 20.5 centimeters from the top of the poster board starting at the right hand side of the 10 cm segment that you just drew. Connect the endpoints of the two segments to create a right isosceles triangle
Step 4:
Using the hypotenuse of the first triangle, create another right triangle on top of the previous hypotenuse
Step 5:
Continue to repeat this process of connecting and constructing new triangles with a side length of 10, using the previous hypotenuse as the other side, there will be 17 triangles total
Step 6:
Detail your Pythagorean Spiral with a design
Step 7:
Calculate the hypotenuse of the first 5 triangles on a back of your project
