The SAS or side angle side criterion states that two triangles are similar if two pairs of corresponding sides are in the same ratio and their included angles are congruent You ll use GeoGebra to demonstrate this Use the GeoGebra activity to complete each step below For help watch these short videos about using GeoGebra to draw points lines and angles and use the measurement tools Part A Create a random triangle AABC Record the lengths of sides BC and CA and the measure of the included angle Take a screenshot of your dilation save it and insert the image below the table BIUX X 10pt V AVA 2BCA side BC side CA Measure
