Request for Data

Teacher Notes

1. This activity should be completed individually.

2. The approximate time for completion is 15 – 20 minutes.

3. Students should have access to protractors.

4. Answers:

   • Launch #1
     m < A = 55°
     m < B = 90°
     m < C = 35°

   • Launch #2
     m < A = 70°
     m < B = 90°
     m < C = 20°

For Launch #1, the sum of the measures of the angles is 55° + 90° + 35° or 180°.

For Launch #2, the sum of the measures of the angles is 70° + 90° + 20° or 180°.
