Question

Given: C is a point on the perpendicular bisector, l, of AB.

Prove: AC = BC

Line l is a perpendicular bisector of line segment A B. It intersects line segment A B at point D. Line l contains point C.
Use the drop-down menus to complete the proof.

By the unique line postulate, you can draw only one segment,
. Using the definition of
, reflect BC over l. By the definition of reflection, C is the image of itself and
is the image of B. Since reflections preserve
, AC = BC.

To complete the proof, we will fill in the drop-down menus as follows:

1. By the unique line postulate, you can draw only one segment, **AB**.
2. Using the definition of **perpendicular bisector**, reflect BC over l.
3. By the definition of reflection, C is the image of itself and **B'** is the image of B. Since reflections preserve **lengths**, AC = BC.

This concludes the proof. Given that C is on the perpendicular bisector of AB, and making use of the properties of reflections, we have shown that AC is equal to BC.
