Activity In this activity you will use the GeoGebra geometry tool to explore the side side side criterion for triangle congruence If you need help watch these short videos about using GeoGebra to measure and create points lines and angles C Part A Create a triangle using the vertices A 4 3 B S 2 and C 2 6 Measure the lengths of all three sides on the triangle using the distance tool and record them in the table BIY X X 14pt Bwww Side Length AB BC AC Space used includes formatting 560 15000 EFFE Part B Keep the triangle that you created in part A You will now copy the triangle to a different location on the grid using three of its sides Submit In a different place on the grid draw a new line segment that is parallel to and has the same length as AB Label this segment DD Next copy AC and BC A reliable way to do this is to draw a circle centered on each endpoint of your new line segment Make the radius of each circle equal to each of the lengths of the two remaining line segments on the original triangle One of the intersection points of the two circles marks the third vertex of your new triangle Place a point on the intersection and label the point F Finish copying the triangle by drawing a polygon through the three points that you ve established BIY X X 15px You should now have two triangles on the grid What do you notice about the two triangles in terms of their size and shape V AVA EF a 8
