This is a packet of 8 worksheets all about triangles.
1 - Makes use of the angles summing to 180 degrees.
1 - Classifying triangles using their angle measurements.
1 - Using the distance formula to classify triangles and setting up algebraic equations to determine information on equilateral triangles.
1 - Determining angle measurements with algebraic expressions. If angle M is twice the size of angle N...
1 - Determining interior and exterior angles of triangles.
2 - Determining values of isosceles triangles. Both worksheets are very similar to each other but all problems are different. Both worksheets have one proof in addition to determining values of the isosceles triangles.
1 - Determining if 3 lengths could make a triangle. (This also review problems of writing equations and making use of the order of operations.)
