Need help on perpendicular bisectors!:(
You'll find lots of Khan video explanations here.

What is a transformation that creates a mirror image?
Sure! I can help you with perpendicular bisectors.
A perpendicular bisector is a line or a segment that divides another line segment into two equal parts at a right angle. It is commonly used in geometry. To understand how to find and work with perpendicular bisectors, here's a step-by-step explanation:
1. Start with a line segment: Let's say you have a line segment AB.
2. Find the midpoint: To find the midpoint of the line segment, mark a point exactly halfway between points A and B. This point is called the midpoint, and we'll call it M.
3. Construct a perpendicular line: Draw a line that starts from the midpoint M and is perpendicular to the line segment AB. To do this, use a compass or any straightedge tool to create a right angle with line segment AB. This line is the perpendicular bisector of AB.
4. Label the perpendicular bisector: Mark the intersection point of the perpendicular line and the line segment AB. This point is the midpoint of AB, so we'll label this point M. The perpendicular bisector is the line that passes through point M and is perpendicular to line segment AB.
By following these steps, you can easily construct a perpendicular bisector for any given line segment. Once you have the perpendicular bisector, you can use it in various geometric problems and proofs.
