This worksheet replaces a lecture: instead of talking through how to use ASA and SAA to prove triangles congruent, I just open class with a 15-minute mini-lesson showing them the basics, and then I have them work on this worksheet. It also includes a novel explanation of why "SSA" doesn't work.
I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.
The file includes spiral review problems.
This worksheet is intended to be written on directly.
Please download the pdf preview file first, so you can see exactly what's included; the product file is a word document, which you may personalize for your students.
Immediately before this worksheet, I use the worksheet named 'Proving Triangles Congruent By SAS and HL Fall 2013' (http://www.teacherspayteachers.com/Product/Proving-Triangles-Congruent-By-SAS-and-HL-Fall-2013-1070748
), and immediately after this worksheet, I use the assessment named 'Geometry Quiz Proving Triangles Congruent Fall 2013; 2 versions; 2 pages each' (http://www.teacherspayteachers.com/Product/Geometry-Quiz-Proving-Triangles-Congruent-Fall-2013-2-versions-2-pages-each-1269985
