CongruentTriangles

These snowflakes make a great winter decoration for your

classroom walls or bulletin board. Have students cut out the circle, then answer the questions within

the snowflake.

The following skills are included:

- Writing congruency statements- Using Triangle Sum Theorem- Identifying corresponding parts of

triangles- Using base angles of isosceles triangles- Setting up and solving linear equations

to find missing angle measures

Find the sum of the angle measures in ALL of the triangles in the

snowflake.
