Chapter 8, Problem 11STP

To determine

The length of segment AB according to the Perpendicular Bisector Theorem.

Answer to Problem 11STP

  $AB=2.5\text{ cm}$

Explanation of Solution

Given:

  

Calculation:

Perpendicular Bisector Theorem states that, if a point is present on the perpendicular bisector of a line segment, then it is at the equal distance from the endpoints of the segment.

In the given figure, segment AC is the perpendicular bisector of segment DB.

Therefore;

  $\begin{array}{l}AB=AD\\ AB=2.5\text{ cm}\end{array}$
