Topic. Symmetry

Today we learned about symmetry and mirror image.

• Symmetric shape can be folded along the line of symmetry, so that one half matches the other
• Mirror images are opposite. 
• For example, when you look at yourself in the mirror, left and right are reversed.

Homework
1. How many lines of symmetry does this snowflake has?

2. Tom has a clock on his bedroom wall. There is a mirror on the opposite side wall. The clock only has the ticks to mark the hours. It does not have the numbers (like the one below). One day, Tom looks into the mirror and reads the time from it; then he turns around and reads the clock directly, and he finds the time is the same. What time is it when Tom reads the clock?
