Discovery Activity Lab: Linear Pair and Vertical Angle Relationship
Materials: 2 pieces of Patty Paper per person, Geometry journal,
writing utensil
Method:
1. Fold your Patty Paper to construct a line. Label this line k.
2. Repeat Step 1 to construct a second line that intersects with k.
Call this line m.
3. Label the angles 1, 2, 3, and 4 as follows:
1
3
4
2
4. What do you notice about the angle pairs? Use another piece
of Patty Paper to convince yourself & your group that your
observation is true for all intersecting lines.
5. Write two conjectures in “If…,then…” form. You should have a
conjecture for both Linear Pairs and Vertical Angles.
6. Compare your conjectures with a group near you. Did you
come up with a similar argument for why the conjectures are
always true. Write out one of these arguments.
7. Write up a Math Lab Report for your work in today’s lab.
Your Math Lab Report should include the following sections:
1. Title/Testable Question
2. Materials and Methods
3. Results
4. Discussion of Implications / Example Exercises using the
results
