Let’s go through each shape one by one and count how many sides it has. That will tell us what kind of polygon it is.
Remember:
- 3 sides = triangle
- 4 sides = quadrilateral (like square, rectangle, parallelogram, trapezoid)
- 5 sides = pentagon
- 6 sides = hexagon
- 7 sides = heptagon
- 8 sides = octagon
Now let’s look at each number:
1. This shape has 4 equal sides →
square (a type of quadrilateral)
2. This shape has 3 sides →
triangle
3. This shape has 4 sides, opposite sides are parallel →
parallelogram (also a quadrilateral)
4. Let’s count the sides: 1, 2, 3, 4, 5, 6, 7, 8 →
octagon
5. This is a triangle with a right angle → still a
triangle
6. Another 3-sided shape →
triangle
7. Has 4 sides, only one pair of parallel sides →
trapezoid (quadrilateral)
8. Count the sides: 1, 2, 3, 4, 5 →
pentagon
9. 4 sides, opposite sides parallel →
parallelogram (quadrilateral)
10. 3 sides →
triangle
11. 4 sides, all angles are right angles →
rectangle (quadrilateral)
12. Count the sides: 1, 2, 3, 4, 5, 6 →
hexagon
We can write the name of each polygon based on side count or specific type if it’s common (like square, rectangle, etc.).
Final Answer:
1. Square
2. Triangle
3. Parallelogram
4. Octagon
5. Triangle
6. Triangle
7. Trapezoid
8. Pentagon
9. Parallelogram
10. Triangle
11. Rectangle
12. Hexagon
