Symmetry in Geometrical Shapes Powerpoint Presentation (PPT)/Lesson/Slides

Contains 31 slides

Objective: The student will be able to identify whether a given shape has symmetry, to draw the line of symmetry, how many lines of symmetry a shape can have and the type of symmetry the shape has like horizontal, vertical and diagonal.

The Presentation contains:

The symmetry, lines of symmetry and the types of lines of symmetry of the given geometrical shapes.
