Title: Pythagoras lived in the 500's BC,
1Pythagoras lived in the 500's BC, and was one of
the first Greek mathematical thinkers. He had a
group of followers known as the Pythagoreans who
followed him around and taught other people what
he had taught them.

2Pythagoreans were interested in philosophy, but
especially in music and mathematics, two ways
of making order out of chaos. Music is noise
that makes sense, and mathematics is rules for
how the world works.

that the Pythagorean Theorem was true.

4The Pythagorean Theorem says that in a right
triangle, the sum of the squares of the two
right-angle sides will always be the same as the
square of the hypotenuse (the long side). A2

5A Tale of Three Cities The Pythagorean Theorem
Step-by-Step Instructions
- Using Google Maps, find three cities that form a
right triangle. Left-click and hold the mouse to
move the map to any location on the planet. Zoom
in and out until the three cities fill the map
window. - Print the map to a printer or print to a PDF
creator program. Many of these programs are
available for free. If you are using the PDF
method, instead of saving the map as a PDF, use
the PDF creator software to save the map as a
JPEG (photo). Save it into a specific folder.
Next, in that folder right-click on the map
photo, choose copy and then open a new
Presentation document where you will paste the
map onto a slide. - On the printed map, use a straight edge to draw a
right triangle between the three cities. If you
are using the PDF/JPEG method, use your
Presentation software to open and paste a right
triangle on top of the JPEG map. You can edit
the triangle using the Format Shape function
(remove the fill, the thicken the line, change
the line color, etc.) - On a separate slide, insert a Right Triangle,
then add labels for the three sides and the three
City Names. - On another slide, write out the definition for
the Pythagorean Theorem (see example). - On the same slide, use a Distance Finder
website to find the actual distance between the
cities on side a. and the cities on side b. of
the Right Triangle (see example). - Use the Pythagorean Theorem to solve for the
distance of side c (see example). - On this same slide, give the name of side c.
- Next, solve the following problem. Traveling at
an average rate of 50 miles per hour, calculate
how long it will take to make a round trip
journey to all three cities, including an 8-hour
sight-seeing tour in each city. Show this on a
separate slide. - 10. Using Custom Animation in Microsoft
Powerpoint, create a presentation in which you
move a vehicle around to each city on your map.
Choose a vehicle using Clip Art or a photo. - 11. As your vehicle reaches each city, stop and
present 10 facts about that city (see list
provided). Show these facts on a separate slide
for each city.

The first step is to go to Google Maps and use
the Zoom tool to zoom in and out until you find
three cities that form a right triangle.
City 1
City 3
City 2

A Right Triangle placed on top of a JPEG photo
of a Google Map.
Students may print the Google map to a printer
and use a ruler to draw a right triangle on the
map or print the map to a PDF creator program and
save it as a JPEG photo. If the PDF method is
used, students can copy the map into the
presentation software and then insert a right
triangle on top of the map as shown here using
the Insert gt Basic Shapes command.

Students must draw a right triangle in the
presentation software with labels for the cities
and the sides of the triangle.

10A Tale of Three Cities The Pythagorean Theorem
The equation for the
Pythagorean Theorem is _____________________
Example
Use a Distance Finder website to find The
distance between City 1 and City 2 (Side a.)
___________ miles. The distance between City 2
and City 3 (Side b.) ___________
miles. Using the equation for the Pythagorean
Theorem, solve for the distance between City 1
and City 3 (Side c.). 232 miles2 269 miles 2

The distance between City
1 and City 3 ____________ miles. Side c is
called the _______________________

In our example, the total distance is 232 miles
269 miles 355 miles 856 miles
A nice little getaway.
12A Tale of Three Cities The Pythagorean Theorem
Solve this problem.
You will make a round trip journey to all three
cities traveling at an average rate of 50 miles
per hour. Additionally, you will stay 8 hours in
each city on sightseeing tours. How long will
the trip take? _________ hours.
13If we know the distance (miles) and the rate
(miles per hour), we can find the time (hours)
based on the following formula
Distance Rate x Time d r x t
856 miles 50 miles per hour x t
t 17 hours, then add 24 hours 41 hours

Using clip art or a photo, insert a vehicle onto
your map. Move it around to all three cities
using Custom Animation. Stop the animation after
each leg of your trip, and go to the facts for
that city.
