Problem Description:
The image provided is a fact sheet for Year 3 Numeracy, focusing on
two-dimensional shapes. It lists various shapes along with the number of sides each shape has. The task appears to be related to identifying and understanding these shapes based on their properties.
Solution Explanation:
#### Step 1: Understanding Two-Dimensional Shapes
Two-dimensional (2D) shapes are flat figures that have length and width but no depth. They are defined by their sides and vertices (corners). The number of sides determines the name of the shape.
#### Step 2: Analyzing the Provided Shapes
The image lists several 2D shapes along with the number of sides they have. Let's break them down:
1.
Triangle:
- Sides: 3
- Properties: A triangle has three straight sides and three angles.
2.
Square:
- Sides: 4
- Properties: A square has four equal sides and four right angles (90° each).
3.
Rectangle:
- Sides: 4
- Properties: A rectangle has four sides with opposite sides being equal and four right angles (90° each).
4.
Pentagon:
- Sides: 5
- Properties: A pentagon has five straight sides.
5.
Hexagon:
- Sides: 6
- Properties: A hexagon has six straight sides.
6.
Heptagon:
- Sides: 7
- Properties: A heptagon has seven straight sides.
7.
Octagon:
- Sides: 8
- Properties: An octagon has eight straight sides.
8.
Nonagon:
- Sides: 9
- Properties: A nonagon has nine straight sides.
9.
Decagon:
- Sides: 10
- Properties: A decagon has ten straight sides.
#### Step 3: Observing Patterns
- The names of the shapes follow a systematic pattern based on the number of sides:
- "Tri-" means 3 (triangle).
- "Quad-" means 4 (square, rectangle).
- "Penta-" means 5 (pentagon).
- "Hexa-" means 6 (hexagon).
- "Hepta-" means 7 (heptagon).
- "Octa-" means 8 (octagon).
- "Nona-" means 9 (nonagon).
- "Deca-" means 10 (decagon).
#### Step 4: Solving the Task
The task likely involves identifying or drawing these shapes based on their names or the number of sides. Since the problem isn't explicitly stated, we can infer that the goal is to understand and recognize these shapes.
Final Answer:
The solution involves recognizing and understanding the relationship between the names of the shapes and the number of sides they have. Here is a summary:
-
Triangle: 3 sides
-
Square: 4 sides
-
Rectangle: 4 sides
-
Pentagon: 5 sides
-
Hexagon: 6 sides
-
Heptagon: 7 sides
-
Octagon: 8 sides
-
Nonagon: 9 sides
-
Decagon: 10 sides
If the task was to identify or draw these shapes, the student should use this information to correctly label or create the shapes.
