Day 6: Triangles & Special Quadrilaterals

In this lesson we will learn how to classify different types of quadrilateral (four sided figures) and triangles (three sided figures).

Objectives
- Understand the different types of triangle and quadrilateral classifications
- Identify different types of quadrilaterals and triangles

Start this lesson by doing the applet linked below. In this applet you will separate quadrilaterals from non-quadrilaterals and then decide whether they are regular or not.

Now that we have learned about quadrilaterals lets look at triangles. Triangles can be classified by their angles or their sides. Start by working through the applet that classifies triangles by their sides. Then watch the video that discusses the different types of triangle classifications.

For your assignment for this lesson choose one of the following three options. Upload your finished product. If you product is a link, put the link in a word document and upload that document so I can access your finished product.

Option 1
Create a Prezi or Power Point that would teach how to classify triangles and quadrilaterals.

Option 2
Create a short (10 minutes or less) movie that demonstrates all the different types of triangles and quadrilaterals.

Option 3
Create a photo album showing all the different types of triangles and quadrilaterals in real life pictures. Explain what each picture is representing and how you know that it is representing a specific type of quadrilateral or triangle.
