Lines, line segments and rays
Let's draw points, lines, line segments, and rays. We'll also think about perpendicular and parallel lines and identify these in two-dimensional figures. Common Core Standard: 4.G.A.1
Before learning any new concept (mathematical or otherwise), it's important we learn and use a common language and label concepts consistently.
Let's get familiar with the difference between lines, line segments, and rays. Hint: a ray is somewhere between a line and a line segment!
Identify rays, lines, and line segments in geometric figures.
