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

In 2nd grade, you learned to measure lengths. Now we can measure the length around the edge of an object (perimeter) and how much “space” something takes up on a flat surface (area).

In analytic geometry, also known as coordinate geometry, we think about geometric objects on the coordinate plane. For example, we can see that opposite sides of a parallelogram are parallel by by...

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

In this tutorial, we study lines that are perpendicular to the sides of a triangle and divide them in two (perpendicular bisectors). As we’ll prove, they intersect at a unique point called the...
