Lesson details
Key learning points
- The length of the lines do not change when reflected.
- The angles inside an object do not change when reflected.
- When an object is reflected, its image is congruent.
Keywords
Reflection - A reflection of a shape is the mirror image of the shape. An object is reflected when it is flipped over a fixed line.
Sense - The sense of an object is the direction of the orientation of the object.
Common misconception
Just because the sense has changed, it doesn't mean a reflection has occurred.
If an image has a different sense to its object, there has definitely been a reflection - the line of reflection may be at an obscure angle.
