### 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.
 Q 1: Are the two triangles in the figure congruent? (hint: sometimes you have to turn the figure around to see if it is congruent with another)yesno Q 2: When a figure can be folded in half and both halves match the figure is said to bedifferentsymmetricalexact match Q 3: In a symmetrical figure the folded line is calledradiusthe line of symmetrydiameter Q 4: Two figures that are exactly the same shape and size are said to bedifferentsimilarcongruent Q 5: Are the two triangles in the figure congruent?TrueFalse Q 6: How many lines of symmetry does a circle have?159010more than you can count Question 7: This question is available to subscribers only!
