Identifying Line Symmetry in Geometric Figures

This lesson teaches how to identify line symmetry in geometric figures by folding them into matching parts. It covers the three types of symmetry lines: horizontal, vertical, and diagonal. The lesson addresses common misunderstandings and demonstrates how to determine symmetry lines in a complex figure composed of a hexagon and triangles. By examining the figure, students learn to identify one horizontal, one vertical, and four diagonal lines of symmetry, totaling six lines of symmetry.

What are the three types of lines used to determine the symmetry of a geometric figure?

• Parallel, Perpendicular, Curved

• Horizontal, Vertical, Circular

• Straight, Curved, Zigzag

• Horizontal, Vertical, Diagonal

What is crucial to remember when identifying a line of symmetry in a figure?

• The line must be colorful

• The figure must be folded into matching parts

• The line should be at the edge of the figure

• The figure should be rotated

How is a horizontal line of symmetry identified in a geometric figure?

• By drawing a line around the perimeter

• By drawing a diagonal line

• By drawing a line from left to right through the center

• By drawing a line from top to bottom

What is the result when a vertical line of symmetry is applied to a geometric figure?

• The figure is divided into two matching parts

• The figure remains unchanged

• The figure is divided into four parts

• The figure is divided into three parts

How many diagonal lines of symmetry does the geometric figure have?

• Three

• Two

• Five

• Four
