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,*A*′*B*′*C*′*D*′*E*′, and the line of reflection line AE.- Use the
**Line**tool to create*line Line AE.* - Reflect the polygon over the line AE using the
**reflection tool**. - Use the
**Segment**tool to draw segments connecting each vertex of pentagon*ABCDE*to its image on pentagon*A*′*B*′*C*′*D*′*E*′ - 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 ) - 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.

**In your Google doc:**copy, paste and answer each of the following questions:- 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?
