SAS Criterion for Similar Triangles 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 . Print Part A Create a random triangle, AABC. Record the lengths of sides BC and CA d the measure of the included angle. Take a screenshot of your dilation, save it, and insert the image below the table.
