# Pythagorean Theorem Photo Essay

### By: Madalyn Frank

## Jobs the Pythagorean Theorem is used in!

Agricultural workers/ farmers use the pythagorean theorem when they need to draw accurate lines that help show growing spaces to determine how large of an area they have and how much they can plant in that field. If they work with farmers, or just inspect farms, or actually work on a farm they all have to use the pythagorean theorem.

Surveyors also use this as a very important part of their job. Surveyors use the pythagorean theorem to measure out people’s property lines and to be able to measure a boundary line

quickly would be very helpful.

Engineers, use this almost daily to find out the lengths of whatever they are engineering. They use this to help them find their measurements.

Construction Workers, use the pythagorean theorem everyday to make measurements specifically on the corners of an object. Such as finding out the pitch of a roof.

Architects use this any time they use a right triangle in a design and they need to find the measurement.

Sports such as football use it because it will help find the quickest way for a defender to meet up with the person with the ball to tackle them. Also when you have to find the distance you need to throw the ball in baseball.## Square Root

Here are some examples:

2x2=4 3x3=9 4x4=16 5x5=25 6x6=36 7x7=49 8x8=64

9x9=81 10x10=100 14.14x14.14= 200 24.5x24.5=601.8

## Starting point 20.5 cm from one side of the paper and 27.5 cm from the other side of the paper put a dot here and you will have your starting point. | ## 1st triangle Draw a 10 cm long line straight out to the right from your starting point. Next, creating a right triangle or a 90 degree angle draw another line or side of the triangle with a length of 10 cm. Then, connect that side that you just finished drawing back to the starting point using a ruler for straight edge to draw the hypotenuse of the triangle. | ## 2nd triangle For this triangle the hypotenuse of the first triangle becomes a leg of this triangle. You then create the second leg of this triangle is by adding a 10 cm length line creating a right angle again just like the first triangle. Lastly, connect the leg to the starting point to create the hypotenuse for this triangle and a leg of the next. |

## Starting point

## 1st triangle

## 2nd triangle

## Drawing More Triangles! I drew the rest of the triangles just like the first two. The difference between the triangles are that the hypotenuse of the last triangle or the leg of the new triangle keeps getting larger. | ## Continuing... | ## More Triangles!!! |
