# BPW Inv 1.1 - Line Reflections

In your BPW book or BPW online book link, open to Inv 1.1 (pg 10) and use Geogebra to answer the Part A questions 1 - 4 for pentagon ABCDE after making image, ABCDE′, and the line of reflection line AE.
1. Use the Line tool to create line Line AE.
2. Reflect the polygon over the line AE using the reflection tool .
3. Use the Segment tool to draw segments connecting each vertex of pentagon ABCDE to its image on pentagon ABCDE
4. Use the intersect tool to show intersection point of segments you drew in step three and line AE.(go to and in dropdown menu find )
5. Measure lengths of A to intersection point and A' to intersection point using (under dropdown menu) and angles (click on three points you want to measure.

• ﻿ ﻿﻿How are measures of the line of reflection AE and lines between all points and their image (A and A') related?
• How are the distances of a line from point to line of reflection and image to line of reflection ?
• Which points are in the same location as their image under this reflection?
