Essential stuff for describing the world around you 1 Lines and angles 2 Related angles What about angles bigger than 360 degrees? 3 Triangles See if it's really true, and then prove it! They have two equal sides, but what about their angles? In triangles, sides and their opposite angles are related! 4 Triangle congruence and similarity

Geometry (from Ancient Greek γεωμετρία (geōmetría) 'land measurement'; from γῆ (gê) 'earth, land' and μέτρον (métron) 'a measure') [1] is a branch of mathematics concerned with properties of space such as the distance, shape, size, and relative position of figures [2]
- Geometry -- from Wolfram MathWorld
Geometry is the study of figures in a space of a given number of dimensions and of a given type The most common types of geometry are plane geometry (dealing with objects like the point, line, circle, triangle, and polygon), solid geometry (dealing with objects like the line, sphere, and polyhedron), and spherical geometry (dealing with
