# 4.G.A.1 Lesson Plans

Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

## Coherence Map of 4.G.A.1

The Coherence Map shows the relationships among the Common Core Standards. The Lumos coherence map not only provides graphical representation and convenient navigation within the standards map but also access to thousands of engaging learning & lesson plan resources such as Practice questions, Videos, Books and Infographics related to every standard. It helps educators and students visually explore the learning standards. It's an effective tool to helps students progress through the learning standards. Teachers can use this tool to develop their own pacing charts and lesson plans.

## TOPICS RELATED TO POINTS, LINES, RAYS AND SEGMENTS

### What are geometry points?

A point in geometry is a location. it has no length i.e. no width, no period and no depth. a point is proven via a dot. a line is defined as a line of points that extends infinitely in directions.

### How many points does a ray have?

Rays are generally named in methods: by means of two points. within the discern at the top of the web page, the ray could be known as ab due to the fact starts at point a and passes via b on its way to infinity. don't forget that factors are typically labelled with single top-case (capital) letters.

### How do you do line segments?

In geometry, you may write a line segment using the letters for every of the give up factors and a line over the top of the letters. as an example, in case your end points had been a and b, you then might write your line phase ab with a line over the top.
