BRAIN BLITZ/Warm-UP
Label each of the quadrilaterals with its appropriate name:
For the following questions, answer “sometimes,” “always,” or “never” :
_______________ A trapezoid is a parallelogram.
_______________ A rectangle is a parallelogram.
_______________ A square is a rhombus.
_______________ A rhombus is a square.
_______________ A rectangle is a rhombus.
Short Answer:
Which quadrilateral has only ONE set of parallel sides?
Which two quadrilaterals MUST have 4 right angles?
Which two quadrilaterals MUST have 4 congruent sides?

2. Plot and label the following ordered pairs on the coordinate plane.
A (2, 3) B (3, 4) C (4, 3) D (3, 1)
Connect the dots.
Write the best name
for the quadrilateral:

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

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

5. Let’s focus on translations . . .
Rotation--
Dilation--
is a turn. A AI
is a change in size. A AI

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

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

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

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

11. If point A is located at (2, 5) and is translated three units to the left and two units up, where would A1 be?
If point A is located at (-4, 2) and is translated five units to the right and four units down, where would A1 be?
RIGHT or LEFT changes X!!
UP or DOWN changes Y!!
(-1, 7)
RIGHT or LEFT changes X!!
UP or DOWN changes Y!!

15. IXL: Y.2 & Y.3 Perform the following translations:
This means two units
to the right and
four units down!
Perform the following translations:
Translate the figure (2, -4): ) Translate the figure (-3, 1):
3) Translate the figure (-4, -4): ) Translate the figure (6, -2):
Right or left changes x! Up or down changes y!
If point A is located at (2, 5) and is translated three units to the left and two units up, where would A1 be?
