Exploring Geometry Vocabulary

This video tutorial covers the basics of geometry, including definitions and properties of points, lines, rays, planes, and angles. It explains collinear and coplanar points, congruent segments, and the segment addition postulate. The video also introduces the distance and midpoint formulas, as well as perpendicular and parallel lines. Various types of angles, such as right, acute, obtuse, and straight angles, are discussed, along with concepts like vertical angles, complementary and supplementary angles, and linear pairs.

What is a point in geometry?

• A location with size and shape
