A point is a fundamental concept in geometry. It is a precise location in space, represented by a dot. In geometry, a point has no length, width, or height - it is simply a position.

1. A point has no dimension.

2. It is represented by a dot.

3. It is named by a capital letter.

In geometry, a point is typically named using a capital letter. For example, a point can be named as point A, B, C, etc.

In a coordinate plane, a point is represented by an ordered pair (x, y), where x is the horizontal distance from the origin and y is the vertical distance from the origin.

- How is a point represented in a coordinate plane?

1. Identify the point in the following coordinate pairs: (3, 5), (-2, -4), (0, 0).

2. Name three points in the given figure: [insert an image of a geometric figure with points labeled A, B, and C]

Connections to the Grade 7 Focal Points (NCTM)

Measurement and Geometry: Students connect their work on proportionality with their work on area and volume by investigating similar objects. They understand that if a scale factor describes how corresponding lengths in two similar objects are related, then the square of the scale factor describes how corresponding areas are related, and the cube of the scale factor describes how corresponding volumes are related. Students apply their work on proportionality to measurement in different contexts, including converting among different units of measurement to solve problems involving rates such as motion at a constant speed. They also apply proportionality when they work with the circumference, radius, and diameter of a circle; when they find the area of a sector of a circle; and when they make scale drawings.
