# 4.1 quadratic functions and transformations homework answers

### Question:

What is the point of symmetry in a parabola?

### Answer:

The line that divides a figure into two parts that are mirror images of each other is its axis of symmetry. The axis of symmetry is a straight line in your mind that splits a shape into two identical parts, one of which is a mirror image of the other. When folded along the axis of symmetry, the two parts end up on top of each other. The straight line is also known as the line of symmetry or the mirror line. This line can go straight up or down, or it can go at an angle. The word “symmetry” means “balance.” You can use symmetry in a lot of different ways and places. When the shape is folded along the line of symmetry, the parts that are the same end up on top of each other.
