Triangle Relationships-Classifying Triangles

Introduction

By the end of this webquest, you will be able to:

Classify Right, Obtuse, and Acute angles and Triangles
Be able to Draw and Measure Angles
Identify Parts of a triangle

Task

Students will record measurements of angles and triangles.

Students will learn how to use a protractor correctly and efficiently.

Students will work with a partner to create a PowerPoint, Prezi, Powtoon, etc. to demonstrate their new knowledge regarding the classifications of triangles.

Process

#1) Watch the Powtoon below

#2) Go to http://studyjams.scholastic.com/studyjams/jams/math/geometry/classify-angles.htm and complete the tutorial step-by-step and then the "Test Yourself" section. Screenshot a copy of your results and save it on your Google Drive to insert into your presentation later.

#3) Review the following websites to further your knowledge of classifications of triangles (you do not need to do the sketchpad activities)

http://www.geom.uiuc.edu/~ekeel/Project/tri1.html

#4) When you feel you are ready, visit the following website to practice classifying triangles by their angles. You must classify 100 triangles. Click on the button to Report your totals and email the page to bolling@hamilton.k12.mo.us.

#7) Pick a partner and create a digital presentation that covers this lesson regarding parts of triangles, measuring angles using a protractor, and how to classify triangles by their angle measurements and/or by their sides. You may use any digital means you wish. Remember the few items throughout this web quest that need to be inserted into your presentation somewhere.
