| Geometry
Geometry is the branch of mathematics that involves studying the shape,
size, and position of geometric figures. These figures include plane (flat)
figures, such as circles, triangles, and rectangles, and solid (three-dimensional)
figures, such as cubes, cones, and spheres.
The name geometry comes from two Greek words meaning earth and to measure.
The world is full of geometric shapes and patterns.
Sample some of the following activities to learn more about geometry.

People To See
Euclid
of Alexandria
Spend time with Euclid. He was a Greek mathematician, born about 300 BC.
He is the man to see about plane geometry.
Pythagoras
of Samos
Meet Pythagoras. He was born about 569 BC on the island of Samos off the
coast of Greece. He is known for being a mathematician, but he was really
more of a philosopher.
August
Ferdinand Möbius
Get to know August Ferdinand Möbius. He was a German mathematician
who focused on analytical geometry. Introduce students to his Möbius
strips.
Euclid:
The Father of Geometry
Perhaps antiquity’s most prominent mathematician, Euclid of Alexandria
is best known for his treatise on mathematics entitled The Elements, which
arranged and perfected many geometric theorems. The beauty and symmetry
of Euclid’s work was even celebrated by poet Edna St. Vincent Millay
in her poem “Euclid
Alone Has Looked on Beauty Bare.”
Things To Do
Introduction
to Geometry

Geometry
Flashcards
Use these interactive flashcards to test your knowledge of geometry.
Geometry Problem
of the Week
Have students solve a new geometry problem each week. Students can submit
solutions by using the submit link at the bottom of each problem. The
answer to each problem is posted the following week. You can also browse
through the archives of previous problems and solutions.

Jokes
Impress your friends with good, quality geometry jokes. What did the little
acorn say when he grew up? ----"Geometry"
Geometry
Junkyard
Although Euclidean geometry, in which every line has exactly one parallel
through any point, is most familiar to us, many other geometries are possible.
Particularly important is hyperbolic geometry, in which infinitely many
parallels to a line can go through the same point. Find out more.

Pi Page
This site refers to pi as "the world's most delicious number less than
5". Find out more.
Solid
Geometry Online
Have students create their own 3 dimensional objects such as a decahedron,
a dual cube, hexagonal prism, a hexagonal pyramid, an obelisk, an octagonal
star, a tetragonal pyramid, an icosahedron, and others.
