Line of Symmetry - Indicator: Identify lines of symmetry of a given set of 2-D shapes, and explain why each shape is symmetrical.
Students can attempt to identify the line of symmetry for each irregular shape. They can choose to get feedback on their choice after each image or all images.
Students click on the line segment icon. Then place a dot where they believe the line of symmetry will start. They can then place the last dot where the line of symmetry will end.
After clicking on the arrow button, students can choose to have their answer checked. Immediate feedback is very valuable.
