Grade 1 worksheet on 2-D and 3-D shapes with fun characters and interactive questions.

Let's solve the problem step by step based on the image you provided. This is a Grade 1 worksheet about identifying properties of 2D shapes, specifically focusing on horizontal lines, vertical lines, sides, and corners (vertices).

🔹 Given Example:

The rectangle has:
- 2 horizontal lines
- 2 vertical lines
- 4 corners
- 4 sides

This helps us understand what we're counting.

Now let’s analyze each shape in the questions.

✔ Question 1a: Square

The shape is a square (which is a type of rectangle). It looks like this:

```
┌───────┐
│ │
└───────┘
```

Let’s count:

- Horizontal lines: The top and bottom sides are horizontal → 2
- Vertical lines: The left and right sides are vertical → 2
- Sides: A square has 4 sides → 4
- Corners: A square has 4 corners → 4

✔ Answers for a:
- Horizontal lines: 2
- Vertical lines: 2
- Sides: 4
- Corners: 4

✔ Question 1b: Triangle

The shape is a triangle (right-angled triangle):

```
/|
/ |
/__|
```

Let’s examine:

- Horizontal lines: Only the base (bottom side) is horizontal → 1
- Vertical lines: Only the right side (if it's a right triangle) is vertical → 1
- Sides: A triangle has 3 sides → 3
- Corners: A triangle has 3 corners → 3

> Note: Some triangles may not have perfect horizontal/vertical lines, but in this case, the drawing shows one horizontal and one vertical line forming a right angle.

✔ Answers for b:
- Horizontal lines: 1
- Vertical lines: 1
- Sides: 3
- Corners: 3

❓ Part c: Pentagon (incomplete in your image)

You only showed part of the third shape — it appears to be a pentagon (5-sided shape), but only the top half is visible.

But since it’s cut off, I can’t confirm if it's regular or irregular. However, assuming it’s a regular pentagon (like a house-shaped figure), here's what we'd expect:

- Horizontal lines: Likely 1 (the base), possibly more depending on orientation.
- Vertical lines: Usually 0 unless drawn with vertical sides.
- Sides: 5
- Corners: 5

But without seeing the full shape, it's hard to say exactly how many horizontal/vertical lines.

👉 Since the image cuts off, I’ll stop at a and b, which are fully visible.

✔ Final Answers:

#### a. Square
- Horizontal lines: 2
- Vertical lines: 2
- Sides: 4
- Corners: 4

#### b. Triangle
- Horizontal lines: 1
- Vertical lines: 1
- Sides: 3
- Corners: 3

🎯 Explanation:

- Horizontal lines go left to right (like the horizon).
- Vertical lines go up and down.
- Sides are the straight edges of the shape.
- Corners are where two sides meet (also called vertices).

These concepts help young learners understand basic geometry.
