On the screen, we see a triangle ABC in red color.
Observe how the shape of the triangle A’’’B’’’C’’’ (blue color) changes as we move the points A, B and C. Triangle A’’’B’’’C’’’ is the reflection of the triangle ABC in the origin
Questions to think about
1. What is the relation between the co-ordinates of A and A’’’, B and B’’’ and C and C’’’?
2. Find where are the midpoints of AA’’’, BB’’’ and CC’’’
