How do you determine the number of lines of symmetry for this regular polygon?1In this lesson you will learn how to identify line symmetry in regular polygons by folding the figure into matching, or symmetrical parts.2Polygon Lets Review3Regular Polygon Lets ReviewTo determine the lines of symmetry you have to use horizontal, vertical and diagonal lines.I found all the lines of symmetry!XA Common Misunderstanding5HorizontalDiagonalVertical

Line SymmetryLets ReviewDo you think you should add the same animation to the first and second figure as you did to the third? Dan/Huey made it for me, so I am going to say No, I cant recreate it I am not at the level of PPT yet.6The equilateral triangle has 1 vertical line of symmetry. Core LessonLinda: Is that what you wanted to do? If so, on your effect options click auto reverse. Dont see that on the MAC version.7The equilateral triangle has 2 diagonal lines of symmetry. Core Lesson8The equilateral triangle does not have a horizontal line of symmetry. Core Lesson OK here goes9The equilateral triangle has 3 lines of symmetry. 1 vertical and 2 diagonal lines of symmetry. Core Lesson10A square has 2 diagonal lines of symmetry.Core Lesson NICELY DONE11A square has one vertical line of symmetry.Core Lesson12A square has 1 horizontal line of symmetry.Core Lesson13A square has 4 lines of symmetry. There are 2 diagonals, 1 horizontal, and one vertical line of symmetry.Core LessonAn equilateral triangle has 3 lines of symmetry and 3 congruent sides.A square has 4 lines of symmetry and 4 congruent sides.Core Lesson15A hexagon has 6 lines of symmetry. There is one horizontal line, one vertical line and 4 diagonal lines of symmetry.Core Lesson16In this lesson you have learned how to identify line symmetry in regular polygons by folding the figure into matching, or symmetrical parts.17
