Identify Pentagons
⬟ The Magic 5! Geometry is just counting the straight lines. If it has exactly five corners and five sides, it joined the secret club.
Do this: Read the concept below, then try the quiz or activity.
Concept
Shapes have specific names based entirely on how many straight sides they have.
🎯 The Pentagon Rules: 1. It must have straight lines. No curves allowed! 2. It must be closed! No open gaps. 3. It must have exactly 5 sides!
It DOES NOT have to look like a perfect little house. If it is completely squished, bent, or completely weird looking... but it has 5 straight sides connecting to 5 corners... it is legally a Pentagon.
