Introduction to Geometry
A Greek mathematician estimated the size of the Earth using only a few facts about lines, angles, and circles almost 2000 years ago, long before rockets were launched into space or explorers sailed across the world. This course will begin with the fundamentals of geometry, answering questions such as "How large is an angle?" and "What are parallel lines?" before progressing to complex theorems and proofs for 2D and 3D objects. Along the way, you'll discover many methods for calculating the area of a triangle, a shortcut for estimating the number of stones in the Great Pyramid of Giza, and even your own estimate of the size of the Earth.
You will be able to take your own route within each lesson in this course, and you will be able to move between classes to rapidly review previous information. GeometryX includes a conventional high school geometry curriculum, with CCSS (common core) alignment specified where relevant.
What you'll learn:
- How to measure angles, and rules for determining when angles are congruent
- How to prove and apply properties of triangles, quadrilaterals, and other polygons
- How to calculate the areas of polygons, circles, ellipses, and other complex shapes
- How to prove and apply the Pythagorean theorem
- How line segments and angles in circles are related
- How to calculate the volumes and surface areas of three-dimensional solids
