Triangle Congruence - Coloring Activity

Trigonometry Pile Up - Assessment or Activity: Pythagorean and Cosine use

Great tune for teaching the different types of triangles..."Triangular Triangles" by The Bazillions

These hands on geometry lessons are such a great way to help kids see the relationship between the interior and exterior angles in triangles! This free download is simple to use and includes teaching tips and an answer key!

Triangles anchor chart

Love this visual for area and perimeter!

Angle relationships. I would love to do this on the floor of the classroom or in the hallway then have pairs of students run to things like "Vertical angles, alternate interior angles, alternate exterior angles, linear pairs, supplementary angles, congruent angles, ect" as I call them out.

FREEBIE! This activity helps students discover the angle sum property of triangles by cutting off the angles of a triangle and pasting the vertices together, which meet to form a straight line (180Â°).

Clearly the limit of this humor is âˆž. Add your face to X and divide by these jokes, and it equals laughs! Solve for X. And don't forget to celebrate every year! Because Pi Day is infinite.

Grade - Year 7 â€“ Year 9 , Subject - Math - These anchor charts cover a variety of angles and triangles, with both pictures and definitions. They explain why angles are measured in degrees, and identifies the parts of an angle. Triangles are explained in a similar way. A great reference to laminate and post for your students on your math wall when teaching this unit.
