# Triangles

# Triangles

Several of the practice suggestions are from iXL – I just learned about this at a math leadership meeting this week as well as it was suggested by a couple of parents on Friday (THANK YOU!). You may do up to 20 practice problems per day without having an iXL account.

When a problem is incorrect, it gives the correct answer AND an explanation/practice for you to “get it”. I see this site a great benefit to use throughout a unit of study.

For most topics, I have linked to the Open Math Reference site which offers not only text but also interactive examples of each.

Classifying Triangles – Sides, Angles

iXL practice on the above go here and see F1, F2, F3

Using Converse of Pythagorean Theorem to Classify Triangles (Triangle Type Quiz

Special Lines/Segments of Trianlges:

Medians, Angle Bisectors, Altitudes, Perpendicular Bisectors

iXL practice on the above see M1, M2, M3

Triangle Congruence – Triangles are congruent if you can slide them around, rotate them, and

flip them over in various ways but can “pile” on top of one another.

Midsegment Investigation– completed by Wednesday – if you are not recognizing any patterns in the chart – please go back and check your slope & distance calculations! Some silly mistakes can cause all of your conclusions to be incorrect~!
