Kindergarten 2D Shapes Worksheet: TRIANGLES - Shape Sort, Shape ... - Free Printable

The image is a fun "I Spy Triangles" activity sheet designed for children to practice identifying triangles among various shapes and objects. The goal is to find and color all the triangles in the picture.

Let’s go through the image step by step and identify which shapes are triangles:

🔍 Step 1: Understand What a Triangle Is

A triangle is a three-sided polygon with three straight edges and three angles. It can be:
- Equilateral (all sides equal)
- Isosceles (two sides equal)
- Scalene (no sides equal)
- Right-angled, acute, or obtuse

But for this activity, we just need to find any shape that has three straight sides.

🧩 Step 2: Scan the Image and Identify Triangles

Here are the shapes in the image, and whether they are triangles:

1. Top-right triangle with a face → ✔ Triangle
(Clearly a large triangle with a smiling face)

2. Tree → ✘ Not a triangle
(It's a leafy tree, not a geometric triangle)

3. Clock → ✘ Circle
(Round clock with Roman numerals)

4. Dice → ✘ Square
(6 dots on a square die)

5. Ruler → ✘ Rectangle
(Straight ruler, not a triangle)

6. Two mountain peaks → ✔ Triangles
(Both mountains are triangular in shape)

7. Bicycle in a square → ✘ Square frame
(The bike is inside a square; no triangle here)

8. Tent → ✔ Triangle
(Roof of the tent forms a triangle)

9. Donut → ✘ Circle
(Round donut with icing)

10. Pizza slice → ✔ Triangle
(Classic triangular slice of pizza)

11. Watermelon slice → ✔ Triangle
(Triangular wedge of watermelon)

12. Gift box with bow → ✘ Rectangle
(Box is rectangular; bow is curved)

13. Diamond (rhombus) → ✘ Not a triangle
(Four sides, even though it looks like two triangles, it's one rhombus)

14. Car → ✘ Rectangle and circle
(Vehicle made of rectangles and circles)

15. Football → ✘ Oval
(American football is oval-shaped)

16. Exclamation mark triangle → ✔ Triangle
(Triangle with an exclamation point inside — still a triangle!)

17. Compass → ✘ Circle with a triangle pointer?
(The compass is circular, but the pointer might be triangular — check carefully)
→ Actually, the compass dial is round, and the arrow is not clearly a triangle — probably not counted.

18. Pyramid-like shape (under gift) → ✔ Triangle
(Looks like a party hat or pyramid — triangular base)

19. Book stack → ✘ Rectangles
(Stacked books, rectangular)

20. Another triangle at bottom-left → ✔ Triangle
(Party hat or cone-shaped object — triangular)

✔ Final List of Triangles to Color:

From the above analysis, here are the triangles you should color:

1. Top-right happy triangle
2. Left mountain peak
3. Right mountain peak
4. Tent roof
5. Pizza slice
6. Watermelon slice
7. Exclamation mark triangle
8. Party hat / pyramid shape (bottom left)
9. Small triangle near bottom (party hat style)

> Note: Some may argue about the diamond/rhombus — but it's not a triangle, so do not color it.

---

✔ Summary: Total Triangles = 9

You should color these 9 shapes:

- Happy triangle (top right)
- Two mountains
- Tent
- Pizza slice
- Watermelon slice
- Exclamation mark triangle
- Party hat (bottom left)
- Another small triangle near the bottom (possibly a second party hat or cone)

💡 Tips for Kids:

- Look for three corners and three straight sides
- Even if it’s part of a bigger object (like a pizza slice), if it’s triangular, it counts!
- Don’t get fooled by shapes that look similar but have more sides (like diamonds or squares)
