3. 5-7 Transformations Course 3 Problem of the Day How can you move just one number to a different triangle to make the sum of the numbers in each triangle equal? (Hint: There do not have to be exactly 3 numbers in each triangle.) Move the 9 to the first triangle.

4. 5-7 Transformations Course 3 Learn to transform plane figures using translations, rotations, and reflections.

6. 5-7 Transformations Course 3 When you are on an amusement park ride, you are undergoing a transformation. Ferris wheels and merry-go-rounds are rotations. Free fall rides and water slides are translations. Translations, rotations, and reflectionsare type of transformations.

7. 5-7 Transformations Course 3 The resulting figure or image, of a translation, rotation or reflection is congruent to the original figure.
