Product Description
This worksheet is designed to replace a lecture on the topic of special right triangles: it walks the kids through the 45-45-90 (isosceles right triangle) and 30-60-90 (half an equilateral triangle) shortcuts.

I start out class with a 15-minute "mini-lesson," giving my students some basic examples of what today's lesson will be about. Once the mini-lesson is over, I have them get to work within their groups on this worksheet.

I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.

I have found that students quickly catch on to the shortcuts. Retaining them or knowing to apply them is a bit tricky, so I have included some "reference information" to summarize the shortcuts for them. I have found that including this sort of reference information on my worksheets in gray helps them to study for upcoming assessments.

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 'Pythagorean Theorem Spring 2014' (http://www.teacherspayteachers.com/Product/Pythagorean-Theorem-Spring-2014-1266774), and immediately after this worksheet, I use the mini lesson named 'Introduction to Trigonometry Worksheet Spring 2014 mini lesson' (http://www.teacherspayteachers.com/Product/Introduction-to-Trigonometry-Worksheet-Spring-2014-mini-lesson-1267154)
