Exercise 46 Page 550

We are searching for a line of symmetry, a line that divides the figure into two pieces that look the same.

Yes

Practice makes perfect

We will investigate if we can draw a line that creates two indentical pieces of the figure. It's called a line of symmetry and, if we can find one, the figure can be folded so one side matches the other. Let's draw a vertical line and see if it's a line of symmetry.

The two pieces do not look the same, one is a arrow and one is a tail. We will draw a horizontal line instead and see if that does the trick.

It is a line of symmetry! The two pieces are identical, both of them have half tail and half arrow. The answer is, therefore, yes, the figure can be folded so one side matches the other.
