How can city planners use coordinate geometry to design efficient layouts for buildings, parks, and streets?

KATE SUSSMAN
Горка: 2
This town is a mess! Traffic is awful and we don't have enough space for all our houses!
Горка: 3

Let's use coordinate geometry to make this city more efficient and smart!

HELLO
Lay down each coordinate to map out the locations precisely.

Each point (x, y) tells us exactly where to build!!
Горка: 5
Geometry coordinates help us plan safe walking distances.
Let's keep the school and playground within a quarter mile.
Горка: 6
Meet Anna - the city planner who is using math to shape cities!
Straight roads? Use slope formulas to keep everything aligned.
If the slope is 1, it’s a perfect diagonal path!
Горка: 7
Shapes like rectangles and triangles are easy to map—and use space efficiently.

hello
hi
We can calculate area right from the coordinates!
Горка: 8
You can use different things such as the distance formula to figure out where to place buildings and areas!
Using geometry, Anna tests how people and cars move through the city.
Look! Less congestion and more green space!
Горка: 9
Thanks to coordinate geometry, the city is now smarter, safer, and more beautiful.
Anna, you’re a math superhero! This town will never forget this.
