Lesson: Points, Lines, and Planes in Space Mathematics • Second Year of Secondary School

In this lesson, we will learn how to identify and model geometric concepts like points, lines, and planes in space along with their properties.

Lesson Plan

Students will be able to

describe the possible configurations for two lines in space: parallel, intersecting, or neither (i.e., skew),
understand and visualize how three noncollinear points or two intersecting lines define a plane,
describe the possible configurations of a line and a plane: a line and a plane intersecting at a point, a line included in the plane, a line parallel to the plane but not included (thus not intersecting),
identify the intersection between a plane and a line or between two or three planes.
