Area and perimeter help us measure the size of 2D shapes. We’ll start with the area and perimeter of rectangles. From there, we’ll tackle trickier shapes, such as triangles and circles.

In this topic, we will learn what an angle is and how to label, measure and construct them. We will also explore special types of angles.

First, we will compare objects by length and measure objects with same-size length units without gaps or overlaps. Next, we will read and interpret bar graphs, tell time on an analog clock, and learn about …

In this series of tutorials and exercises you'll become familiar with Euclidean geometry and terms like scale drawings, parts of a circle, area, angles, and geometric figures.

Let's explore how to measure and calculate different shapes and sizes. We'll learn about areas of triangles and parallelograms, volumes of prisms, and even how to work with angles in triangles.
