Counting sides and vertices on a 2D shape

Teaching Transcript

🎙️

Let's count the sides and vertices on this shape

🎙️

A side is the line that connects two corners of a shape

🎙️

And a vertex is the corner. If there is more than one, we call them vertices

🎙️

Counting the sides, we have 5 sides

🎙️

And counting the corners, we have 5 vertices

This math skill teaches how to count the sides and vertices of a 2D shape. A side is defined as the line segment between two vertices, and a vertex is the corner where two sides meet.
