 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.
     Geometry Definitions
     Triangle Classification
     Properties of Angles and Triangles. Classification of Angles.
      Classification of Triangles
 Part 2
   Explore the Triangle Classification website and create your
    own triangles. Explore the specific properties of each of the
    triangles.

   Part 1
       Complete the chart. To find the properties and definitions of these triangles, visit the given
        websites.

                 Equilateral
   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.
