Show Answer Key & Explanations Step-by-step solution for: Free Symmetry Worksheet for Grade 3 and 4
To solve the problem, we need to identify the name of each shape, count the number of sides, and determine the number of lines of symmetry for each shape. Let's go through each shape step by step.

Shape 1: Triangle


- Name: Equilateral Triangle
- Sides: 3
- Lines of Symmetry: An equilateral triangle has 3 lines of symmetry (each line passes through a vertex and the midpoint of the opposite side).

Shape 2: Pentagon


- Name: Regular Pentagon
- Sides: 5
- Lines of Symmetry: A regular pentagon has 5 lines of symmetry (each line passes through a vertex and the midpoint of the opposite side).

Shape 3: Rectangle


- Name: Rectangle
- Sides: 4
- Lines of Symmetry: A rectangle has 2 lines of symmetry (one vertical and one horizontal, passing through the midpoints of opposite sides).

Shape 4: Kite


- Name: Kite
- Sides: 4
- Lines of Symmetry: A kite has 1 line of symmetry (vertical, passing through the longer diagonal).

Shape 5: Trapezoid


- Name: Isosceles Trapezoid
- Sides: 4
- Lines of Symmetry: An isosceles trapezoid has 1 line of symmetry (vertical, passing through the midpoints of the two parallel sides).

Shape 6: Square


- Name: Square
- Sides: 4
- Lines of Symmetry: A square has 4 lines of symmetry (2 vertical and horizontal, and 2 diagonals).

Final Answer:


\[
\begin{array}{|c|c|c|}
\hline
\text{Name} & \text{Sides} & \text{Lines of Symmetry} \\
\hline
\text{Equilateral Triangle} & 3 & 3 \\
\hline
\text{Regular Pentagon} & 5 & 5 \\
\hline
\text{Rectangle} & 4 & 2 \\
\hline
\text{Kite} & 4 & 1 \\
\hline
\text{Isosceles Trapezoid} & 4 & 1 \\
\hline
\text{Square} & 4 & 4 \\
\hline
\end{array}
\]

So, the final answer is:
\[
\boxed{
\begin{array}{|c|c|c|}
\hline
\text{Name} & \text{Sides} & \text{Lines of Symmetry} \\
\hline
\text{Equilateral Triangle} & 3 & 3 \\
\hline
\text{Regular Pentagon} & 5 & 5 \\
\hline
\text{Rectangle} & 4 & 2 \\
\hline
\text{Kite} & 4 & 1 \\
\hline
\text{Isosceles Trapezoid} & 4 & 1 \\
\hline
\text{Square} & 4 & 4 \\
\hline
\end{array}
}
\]
