Taking a break from social studies to test your MATH skills!

Quizlet, LLC. (2012). Classifying Triangles and
Quadrilaterals. [online image]. Retrieved from http://bit.ly/RisAFS

Over the last two weeks in our math classes, I have introduced you to the classification of triangles and quadrilaterals. To refresh your memory, remember that we started by discussing the classification of triangles. Triangles can be classfied according to their sides or their angles. We explored these concepts further by discussing equilateral triangles, isosceles triangles, and scalene triangles along with the concepts of right angles, obtuse angles, and acute angles.

To further your understanding on classifying and sorting triangles and quadrilaterals, follow the link provided to either re-learn the concepts or test yourself on what you know. This is a great way to study for the test next week!

Curriculum Connection:

Mathematics: Grade 7: Geometry and Spatial Sense

By the end of Grade 7, students will be able to:

Overall Expectations:

• construct related lines, and classify triangles, quadrilaterals, and prisms

Specific Expectations:

• sort and classify triangles and quadrilaterals by geometric properties related to symmetry, angles, and sides, through investigation using a variety of tools (e.g., geoboard, dynamic geometry software) and strategies (e.g., using charts, using Venn diagrams) (Sample problem: Investigate whether dilatations change the geometric properties of triangles and quadrilaterals.)
