Types of Triangles

  1. Drag the vertices of each of the triangles. Record what you notice about the angles and the lengths of the sides of each of the triangles. Based on these observations, what kind of triangle do you think each is?

    Blue:

     

    Green:

     

    Purple:

     

  2. Use the link at the bottom of the web page to go to page 2 of the activity. Drag the vertices of the triangles and explain whether or not the additional information provided agrees with the conclusions you made above for each triangle.

  3. Use the link at the bottom of the web page to go to page 3 of the activity. Again, drag the vertices of the triangles and explain whether or not the additional information provided agrees with the conclusions you made above for each triangle.

    Red:

    Blue:

    Green:

    Purple:

  4. You can move the blue and purple triangles so that they "match up", or are exactly the same in every way (try it!). This is marked on the chart below by the Y. Mark Y or N in each box of the chart to show whether the other pairs match up. Add any comments you have about this part below the chart.
