Introduction

 This topic splash activity is designed to introduce
you to properties of different triangles. You will be
introduced to six different types of triangles, acute,
right, obtuse, isosceles, scalene, and equilateral. You
will search the internet the complete the worksheet
and answer questions based on each one of the
triangles. You will then work in groups and explore
the properties further on an internet activity.
Triangles

 Part 1
 Complete the Triangle Worksheet. To find the properties and
definitions of the different types of triangles, visit these
websites.

   Part 2
   After you have completed the chart, explore the Triangle Classification website, and create your
own triangles. Create each one of the triangles mentioned in the chart. Using the information
given on the website, show that each shape you made is in fact the shape you think it is. Be sure
to show that you have the necessary characteristics of the shape and be able to explain your
reasoning.
