Geometry Math

Join us as we go on a journey into the world of symmetry! Learn about the wonders of line symmetry—or reflection—as you create mirror images and watch how rotational symmetry works in this brief peek into this area of geometry.

Why the familiar equal sign isn’t just a marker of sameness but a gateway into math’s—and humanity’s—most profound questions Math is famous for its equations: 1 + 1 = 2, a2 + b2 = c2, or y = mx + b. Much of the time it can seem like that’s all mathematics is: following steps to show...

From the New York Times-bestselling author of How Not to Be Wrong—himself a world-class geometer—a far-ranging exploration of the power of geometry, which turns out to help us think better about practically everything How should a democracy choose its representatives? How can you stop a...

The Freakonomics of math—a math-world superstar unveils the hidden beauty and logic of the world and puts its power in our hands The math we learn in school can seem like a dull set of rules, laid down by the ancients and not to be questioned. In How Not to Be Wrong, Jordan Ellenberg shows us...

AN INSTANT NEW YORK TIMES BESTSELLER! An ode to triangles, the shape that makes our lives possible Trigonometry is perhaps the most essential concept humans have ever devised. The simple yet versatile triangle allows us to record music, map the world, launch rockets into space, and be...

An illuminating, millennia-spanning history of the impact mathematics has had on the world, and the fascinating people who have mastered its inherent power, from Babylonian tax officials to the Apollo astronauts to the eccentric professor who invented the infrastructure of the online world...

Have you ever wondered about all the shapes it takes to design and build structures like buildings or bridges? Different shapes like squares, triangle and rectangles are used in construction, but which shape forms the strongest? Follow the activity using straws and string to find out which shape is the strongest, sturdiest construction?

An audio tour of the structures and patterns we call "math" This is an audiobook about math, but it contains no numbers. Math Without Numbers is a vivid, conversational, and wholly original guide to the three main branches of abstract math—topology, analysis, and algebra—which turn out to be...

From rectangular ladders to circular rings and hexagonal picnic tables, the park is full of shapes! Fun rhyming text will engage young children as they learn.

The science club has created a big "book bandit" sculpture in the public library. But how did they get the sculpture in through the tiny library window? The librarians offer a prize to whoever can figure out the puzzle. The kids from Sifu Faiza's Kung Fu School know they can win, but it will take all of their geometry skills plus some unexpected cooperation to size up...the book bandit.
