How to identify lines of symmetry. In order to draw/identify lines of symmetry: Locate the center of the 2D shape. Draw a vertical line through the center and check for line symmetry. Draw a horizontal line through the marked center and check for line symmetry. Draw a line from each vertex through the center and check for symmetry.

Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry. Grade 5: Geometry (5.G.B.4) Classify two-dimensional figures in a hierarchy based on properties.

A two-dimensional (2D) shape can be defined as a flat figure or a shape that has two dimensions —lengthand width. Two dimensional or 2D shapes do not have any thickness. 2D figures can be classified on the basis of the dimensions they have.
Fun Fact! A point is zero-dimensional, while a line is one-dimensional for we can only measure its length.
Example 1: Which of the following are 2D shapes? Circle Sphere Cylinder Pentagon Kite Rhombus Solution: Circle Pentagon Kite Rhombus Example 2: State whether true or false. 1. A 2D shape has one dimension. 2. A 2D shape has no thickness. 3. The circle is an example of a 2D shape. 4. We can find the volumeof a 2D shape. Solution: 1. False. A 2D shap...

Example 3: using angles. Show that the hexagon below has no lines of symmetry. Locate the centre of the 2D shape. Show step. Draw a small x x in the centre of the hexagon (this does not have to be exact): Use a ruler to visualise a horizontal and/or vertical line of symmetry through the centre of the shape. Show step.
