Okay, this question asks about the symmetries of this figure.
00:07
So for reflection symmetry, it asks how many lines of symmetry we have, and for this, we just see how many lines we can make that cut this figure into equal halves.
00:18
And the key observation is that the lines are all directly across from each other, so this splits it in half perfectly, this splits it in half, this splits it in half, this splits it in half, this splits it in half, this splits it in half, and this splits it in half.
00:35
So it's just the number of side pairs we have.
00:45
So for reflection, we have 10 sides divided by two sides per pair, or rather per line...
