Are the orange shapes both equal to one-half of the square?
We know the answer to this question will be yes or no. Let’s look at the first square. The dotted line or the fold line shows us where this square has been folded. Does this fold the square into two equal halves? Yes, it does.
Now, let’s look at the second square. Let’s imagine what the square would look like if we fold it along this line. It’s a half. Even though the orange shapes are different in shape, they are both equal to one-half of the square. So, the answer to the question, are the orange shapes both equal to one-half of the square, is yes.
