### Grade 4 - Mathematics12.5 Congruent and Symmetric Figures

 When two figures are exactly the same, they are said to be congruent. When a figure can be folded into equal pieces, then it is said to be symmetric. The line along which the figure is folded is called the line of symmetry. Example: How many lines of symmetry does this figure have? Answer: 4 Directions: Answer the following. Also draw at least five symmetric figures and show their line of symmetry.
