Sides and vertices worksheet - Free Printable

Let’s go through each shape one by one and count how many sides and vertices it has.

---

First shape: Blue square (or rectangle — doesn’t matter, both have same number of sides/vertices)
- Sides: Top, bottom, left, right → 4 sides
- Vertices: The 4 corners where sides meet → 4 vertices

---

Second shape: Yellow triangle
- Sides: Three straight lines → 3 sides
- Vertices: Three corners → 3 vertices

---

Third shape: Green pentagon
- “Penta” means five → so it should have 5 sides and 5 vertices
- Count them: yes, 5 straight sides, 5 corners → 5 sides, 5 vertices

---

Fourth shape: Red hexagon
- “Hexa” means six → 6 sides, 6 vertices
- Count: top, bottom, and four slanted sides → total 6 → 6 sides, 6 vertices

---

Fifth shape: Orange circle
- A circle is curved — no straight sides → 0 sides
- No corners either → 0 vertices

*(Note: In basic geometry for students, we say circles have 0 sides and 0 vertices. Some advanced math might talk about infinite sides, but that’s not what this worksheet wants.)*

---

Sixth shape: Light blue rectangle
- Same as the first shape — 4 sides, 4 corners → 4 sides, 4 vertices

---

Now let’s write down all answers in order:

1. Square/Rectangle → 4 sides, 4 vertices
2. Triangle → 3 sides, 3 vertices
3. Pentagon → 5 sides, 5 vertices
4. Hexagon → 6 sides, 6 vertices
5. Circle → 0 sides, 0 vertices
6. Rectangle → 4 sides, 4 vertices

Final Answer:
Shape | Number of sides | Number of vertices
------|------------------|-------------------
Blue square | 4 | 4
Yellow triangle | 3 | 3
Green pentagon | 5 | 5
Red hexagon | 6 | 6
Orange circle | 0 | 0
Light blue rectangle | 4 | 4
