What is a Square?
Note:
A square is one of the many fundamental shapes you’ll see in math. Squares have special properties that can be very useful in helping you solve a problem. This tutorial introduces you to squares and explains their interesting qualities!
Background Tutorials
-
Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
-
What is a Rectangle?
A rectangle is one of the many fundamental shapes you'll see in math. Rectangles have special properties that can be very useful in helping you solve a problem. This tutorial introduces you to rectangles and explains their interesting qualities!
-
What is a Quadrilateral?
The term quadrilateral is a really fancy sounding name for a certain kind of polygon. Did you know that there are special types of quadrilaterals? Watch this tutorial to learn about quadrilaterals and their special types.
-
What is a Rhombus?
A rhombus is a special kind of quadrilateral. Knowing about the special properties of a rhombus is important to identifying and using these special polygons. This tutorial introduces you to the rhombus and explains its unique qualities. Take a look!

Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
-
What are Acute, Obtuse, Right, and Straight Angles?
Did you know that there are different kinds of angles? Knowing how to identify these angles is an important part of solving many problems involving angles. Check out this tutorial and learn about the different kinds of angles!
-
What are Parallel Lines?
Lines that are parallel have a very special quality. Without this quality, these lines are not parallel. In this tutorial, take a look at parallel lines and see how they are different from any other kind of lines!

Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.
-
What Does Congruent Mean?
If two figures have the same size and shape, then they are congruent. The term congruent is often used to describe figures like this. In this tutorial, take a look at the term congruent!

Prove theorems about parallelograms. Theorems include: opposite sides are congruent, opposite angles are congruent, the diagonals of a parallelogram bisect each other, and conversely, rectangles are parallelograms with congruent diagonals.
-
What is a Parallelogram?
A parallelogram is a special type of quadrilateral with some special properties. In this tutorial, take a look at parallelograms and learn what kinds of quadrilaterals can also be called parallelograms!
