Decagon: a 10-sided shape
A free regular decagon diagram showing 10 sides and 10 vertices. Download the PNG for shape recognition, slides and classroom displays.
UNDERSTAND THE IMAGE
A decagon has 10 sides and 10 vertices.
A decagon is a polygon with 10 straight sides. This diagram shows a regular decagon: all its sides have equal length and all its interior angles are equal. An irregular decagon still has 10 sides, but its sides and angles do not all have to be equal.
Try it in class
- Choose a starting vertex, then count all 10 sides without counting the first side twice.
- Point to a side and a vertex. Explain how they are different.
- Compare this shape with another polygon. What changes when you add one side?
One image, plenty of uses
This is a diagram, not a completed worksheet. Insert the PNG into a slide, resize it in a document, or print it as a teaching visual. Use it in your classroom materials and review it for your learners before use.
