Geometry Culminating Task Due April 3rd

Culminating Activity: Grade 8

For this task, you are going to create a map of a city called PICK A NAME.  The civil engineer who designed PICK A NAME was obsessed with geometric relationships and made the streets cross to demonstrate various line, circle and angle relationships.  Create the detailed map. You must label all streets and the angles that they intersect. Be as creative as you can!

Your street map for PICK A NAME must contain the following:

•         At least 1 pair of parallel streets

•         Two streets that are transversals

•         Two intersections that have an alternate angle relationship

•         Two intersections that have a corresponding angle relationship

•         Two intersections that have an opposite angle relationship

•         One street that meets another to create a pair of supplementary angles.

•         A park that is a quadrilateral, with walking paths that meet perpendicularly

•         A Town Centre that has three quadrilateral buildings. Each building has a path to the centre.

	Level 1	Level 2	Level 3	Level 4
Knowledge: -         I understand how geometric properties can be applied to the real world. -         I included all required geometric properties.
Application: -         I created a street map that has angles that are geometrically correct. -         I solved angle relationship problems involving interacting lines, parallel lines, and transversals. -         I calculated complementary, supplementary, and opposite angles.
Thinking: -         I identified application of geometric properties in the real world.
Communication: -         I included angle relationships that complement each other accurately. -         I labeled all angles names, degrees, and geometric properties correctly.

Complementary and Supplementary Angles

Here is a great video that supports what we were learning in class today about supplementary and complimentary angles.


Remember the 'remembering' trick:

Complimentary angles have a Corner (they add to 90 degrees)
Supplementary angles are on a Straight line (they add to 180 degrees)

Opposite angles -
