In geometry, an endpoint refers to the point at the end of a line segment or the starting point of a ray. It is the point that marks the boundary or extremity of a geometric figure or object.

- An endpoint is a specific point that marks the end or beginning of a line segment or ray.
- For a line segment, there are two endpoints, one at each end of the segment.
- For a ray, there is one endpoint where the ray begins, and it extends infinitely in the other direction.
- Endpoints are usually denoted with a dot or a small symbol to indicate the precise location.

To understand the concept of endpoints better, it's important to practice identifying and working with endpoints in different geometric figures. Here are some key study points to focus on:

- Identifying Endpoints: Practice identifying the endpoints of given line segments and rays.
- Using Endpoints in Geometry Problems: Solve problems involving endpoints, such as finding the length of a line segment or determining the direction of a ray.
- Coordinate Geometry: Explore how endpoints can be represented using coordinates on a coordinate plane.
- Real-life Examples: Look for real-life examples where understanding endpoints is important, such as in construction, architecture, or map reading.

By mastering the concept of endpoints, you'll develop a deeper understanding of geometric figures and their properties.

Geometry (NCTM)

Use visualization, spatial reasoning, and geometric modeling to solve problems.

Use geometric models to represent and explain numerical and algebraic relationships.

Measurement (NCTM)

Apply appropriate techniques, tools, and formulas to determine measurements.

Select and apply techniques and tools to accurately find length, area, volume, and angle measures to appropriate levels of precision.

Develop and use formulas to determine the circumference of circles and the area of triangles, parallelograms, trapezoids, and circles and develop strategies to find the area of more-complex shapes.

Connections to the Grade 6 Focal Points (NCTM)

Measurement and Geometry: Problems that involve areas and volumes, calling on students to find areas or volumes from lengths or to find lengths from volumes or areas and lengths, are especially appropriate. These problems extend the students' work in grade 5 on area and volume and provide a context for applying new work with equations.
