Worksheet 1.1 Points, Lines, and Planes Day 1 Answer Key

This answer key provides detailed solutions to Worksheet 1.1, covering fundamental concepts of points, lines, and planes in geometry. Each answer is accompanied by clear explanations and justifications.

Points, Lines, and Planes Definitions

Point:A point is a fundamental geometric element that has no dimensions and represents a specific location in space. It is denoted by a single letter, such as A, B, or C.

Line:A line is a one-dimensional geometric figure that extends infinitely in both directions. It is defined by two distinct points, and all the points on the line lie in a straight path between these two points. A line is often denoted by two points, such as AB or CD.

Plane:A plane is a two-dimensional geometric figure that extends infinitely in all directions. It is defined by three non-collinear points, and all the points on the plane lie in a flat surface. A plane is often denoted by three points, such as ABC or DEF.

Identifying Points, Lines, and Planes

Points:Points are identified by their coordinates in a given coordinate system. They are represented by a single letter, such as A(2, 3) or B(-1, 5).

Lines:Lines can be identified by two distinct points on the line. They can also be identified by an equation in slope-intercept form (y = mx + b) or point-slope form (y – y1 = m(x – x1)).

Planes:Planes can be identified by three non-collinear points on the plane. They can also be identified by an equation in the form Ax + By + Cz + D = 0, where A, B, C, and D are constants.

Intersection:When a line and a plane intersect, they form a point. When two planes intersect, they form a line.

Parallelism:Two lines are parallel if they never intersect. Two planes are parallel if they never intersect and do not share any common points.

Perpendicularity:A line is perpendicular to a plane if it intersects the plane at a right angle. Two planes are perpendicular if they intersect at a right angle.

Applications of Points, Lines, and Planes

Points, lines, and planes have numerous applications in real-world scenarios:

• Architecture:Designing buildings, bridges, and other structures.
• Engineering:Creating blueprints, calculating distances, and analyzing forces.
• Design:Developing logos, creating artwork, and designing products.
• Navigation:Determining locations on maps and finding directions.
• Computer Graphics:Creating 3D models, rendering images, and designing virtual environments.
