Name:________________________________________________________________________________Date:_____/_____/__________ Label each of the quadrilaterals with its appropriate name: For the following questions, answer “sometimes,” “always,” or “never” : 1._______________ A trapezoid is a parallelogram. 2._______________ A rectangle is a parallelogram. 3._______________ A square is a rhombus. 4._______________ A rhombus is a square. 5._______________ A rectangle is a rhombus. Short Answer: 6.Which quadrilateral has only ONE set of parallel sides? 7.Which two quadrilaterals MUST have 4 right angles? 8.Which two quadrilaterals MUST have 4 congruent sides?

Today’s Lesson: What: transformations (Translations)... Why: To introduce transformations and begin performing translations. What: transformations (Translations)... Why: To introduce transformations and begin performing translations.

4 Types of Transformations: 1)Translation-- 2) Reflection-- What is a transformation?? A transformation refers to a specific way a figure in geometry is either changed or __________________ to create a different image. A AIAI A AIAI moved is a slide. is a flip.

3)Rotation-- 4)Dilation-- A AIAI Let’s focus on translations... A AIAI is a turn. is a change in size.

AAIAI PRE- IMAGE (before) IMAGE (after) We call this “A___________.” First things first... prime

Perform the following translations: 1)Translate the figure (2, -4): This means two units to the RIGHT and four units DOWN!

Perform the following translations: 2)Translate the figure (-3, 1): This means three units to the LEFT and ONE unit up!

Perform the following translations: 3)Translate the figure (-4, -4): This means four units to the LEFT and four units DOWN!

Perform the following translations: 4)Translate the figure (6, -2): This means six units to the RIGHT and two units DOWN!

1)If point A is located at (2, 5) and is translated three units to the left and two units up, where would A 1 be? 2)If point A is located at (-4, 2) and is translated five units to the right and four units down, where would A 1 be? (-1, 7) (1, -2) RIGHT or LEFT changes X!! UP or DOWN changes Y!! RIGHT or LEFT changes X!! UP or DOWN changes Y!!

END OF LESSON The next slides are student copies of the notes for this lesson. These notes were handed out in class and filled-in as the lesson progressed. NOTE: The last slide(s) in any lesson slideshow represent the homework assigned for that day.
