Exercise 57 - Pag. 216

After this lesson, I can…

1. … calculate an angle in a triangle when the other two angles are known.

Goals

Angles of a triangle

1. Draw a random triangle in the corner of your notebook.

2. Color the angles of your triangle.

3. Cut out the triangle with a pair of scissors.

4. Place the angles next to each other. What do you notice?

If you do not have any pair of scissors, then measure all the angles with your protractor and add them.
