This math topic is focused on the understanding of 2D shape symmetry, specifically recognizing how many lines of symmetry various geometric shapes possess. It offers problems related to different 2D shapes, such as hexagons, octagons, and triangles. Each question presents a shape and asks the learner to determine the number of lines of symmetry it has with multiple choice answers, enhancing skills in geometry, particularly in the area of shape classification and symmetry identification.

How many lines of symmetry does this Hexagon have?
Earned ?
🎙️
Are these shapes symmetric, and how many lines of symmetry do they have?
🎙️
Symmetry means you can draw a line and one side of the line is a mirror image of the other. The butterfly has a left and right side that are identical, so it has one line of symmetry.
🎙️
The rabbit has no way to draw a line where one side is the same as the other. So it is not symmetric and has zero lines of symmetry.
🎙️
For this shape, there are 4 different ways to draw lines of symmetry that make one side identical to the other.
