  2. HGEO Warm-up: 9/25 and 9/29 Name: ____________________ Date: ____________ Pd: _____ 1) Plot and label the following ordered pairs. Connect the points. A (-2, 4) B(-3, 1) C(-5, 1) D(-4, 4) 2) What is the name of shape ABCD? ____________________ 3) Identify the ordered pairs for the following: F ( ) G ( ) H ( ) J ( ) 4) Connect the points and identify the name of shape FGHJ. ________________________ FOR LATER USE 1) Translate ABCD _____ units left and ______ units down. 2) Record the coordinates of A’B’C’D’. 3) Write the rule for the transformation. FOR LATER USE 1) Reflect FGHJ over the _______________________. 2) Record the coordinates of F’G’H’J’. 3) Write the rule for the transformation.

  3. Mastery Objectives • We will… • Identify four transformations and perform reflections and translations within the coordinate plane.

  4. Agenda • Copy HW/Study for Quiz • Quiz: Angle and Segment Addition Interactive Notes • Review Transformations • Reflections Guided Practice Whiteboard Activity: Transformations Group Activity • Round Robin Transforming Groups Exit Ticket and Summary

  5. Homework • Radical Reflections and Terrific Translations HW

  6. Coming Up in Geometry Wed 9/30, Thurs 10/1 Transformations: Reflections Fri 10/2, Mon 10/5 (HSA Week) Unit 1 Review Tues 10/6, Wed 10/7 (HSA Week) Unit 1 Test

  19. Round RobinTransforming GroupsRound 1 5 minutes • Write your name in the Round 1 blank. • Draw a parallelogram or trapezoid on the coordinate grid. • Label the preimage. • Fill in the Reflect the shape over the ____________ blank • y-axis • x-axis • Any line (x = ____ or y = _____) Keep the shape on the coordinate grid.

  20. Pass to your left!!

  21. Round RobinTransforming GroupsRound 2 5 minutes Write your name in the Round 2 blank. Reflect the preimage. Label the new image. Write the transformation rule. Fill in the translate the shape blanks. STOP! Keep the shape on the coordinate grid.

  22. Pass to your left!!

  23. Round RobinTransforming GroupsRound 3 5 minutes Write your name in the Round 3 blank. Translate the new reflected shape. Label the new shape. Write the transformation rule. STOP! Keep the shape on the coordinate grid.

  24. Pass to your left!!

  25. Round RobinTransforming GroupsRound 4 5 minutes Write your name in the Round 4 blank. Write the rule for the entire transformation from preimage to final image. How would you write a rule for the reflection? How would you write the rule for the translation? Put them together into one rule! STOP! Keep the shape on the coordinate grid.
