Build a House with Math

Use rectangles, triangles, and coordinates to construct a house — then customize it with windows, trees, and more

Every shape you see in the real world can be described with math. A wall is a rectangle, a roof is a triangle, and a window is a smaller rectangle placed at the right coordinates. In this lesson, you'll see how coordinate geometry turns numbers into pictures.

Press → and watch the AI build a house from scratch — rectangles for walls, a triangle for the roof, and a door. Then you decide what to add: windows, a chimney, trees, a fence, a sun, clouds — anything you can imagine.

Tell the AI what you want to build, and watch it appear on the graph as geometric shapes. This is a creative sandbox — there's no wrong answer, just math making art.

What shapes can I build with coordinates?
You can build any shape using coordinate geometry. Rectangles (boxes) are defined by an edge and a height. Triangles need three corner points (vertices). Line segments connect two points — great for fences, power lines, or tree trunks. Labels add text or emoji at any position. You can even draw circles using function equations like x^2 + y^2 = r^2.
How is a rectangle defined in coordinate geometry?
A rectangle on a coordinate plane is defined by one edge (two endpoints) and a perpendicular height. For example, an edge from (0,0) to (6,0) with height 4 creates a rectangle with corners at (0,0), (6,0), (6,4), and (0,4). The edge can be at any angle — the rectangle extends perpendicular to it.
How is a triangle defined in coordinate geometry?
A triangle is defined by three vertices (corner points). For example, vertices at (0,4), (6,4), and (3,6) form an isosceles triangle — a classic roof shape. The three vertices can be anywhere on the coordinate plane, and the triangle fills the region between them.
Can I use math to draw curved shapes like circles or suns?
Yes! A circle with radius r centered at the origin is described by the equation x^2 + y^2 = r^2. You can shift the center to any point (h, k) using (x-h)^2 + (y-k)^2 = r^2. This is how you can draw a sun, wheels, or any circular object using pure math.
What can it graph?
It can plot explicit, implicit, and parametric functions, add points and geometry, and animate sliders on the same graph.
Can I use voice or a photo?
Yes. You can talk to the tutor, upload a worksheet or handwritten problem, and let the graph update from that input.
Will it explain the steps?
Yes. The AI explains what it is drawing and why, so you see the answer on the graph instead of getting only a final number.
