When two shapes are exactly the same we can say they are ______________
Congruent
Slide
Another word for Rotate:
Turn
Another word for Reflection:
flip
Two shapes are congruent if they are the same _______ and ________
Size and Shape
The two red sides of the triangles are ______________ (2 words)
Corresponding Sides
Describe the following transformation
Translate the triangle 3 units right
Describe the transformation: (the top is the original)
90 degree rotation clockwise
Describe the transformation fully
Reflect over line l
We can use ____________________ to show two shapes are congruent. They are congruent if we can make them lay perfect on top of one another
Rigid Transformations
For this transformation you need: distance and direction
Translation
When we translate we move the shape without ________ or _________ it.
turning or flipping
True or false:
Rotating 180 degrees you NEED the direction
False
Describe how you can reflect an image using tracing paper
trace the shape and the line of reflection, flip your paper and line the line of reflection up.
Your new shape goes where you see it on the tracing paper.
Describe the transformation
90 degress counterclockwise around point A
Flip
Reflect
For a translation we need:
Double points for ALL the detail!
Distance (units)
Direction (left right up or down)
True or false:
270 degrees clockwise is the same as 90 degrees counterclockwise.
False
True or False:
When you reflect the shape has the same orientation as the original.
False, the image is flipped like a mirror image.
Whats the transformation?
Translation
Moving a shape, line or point without changing its size or shape.
Rigid Transformations
Describe the translation fully from A to B:
translate 4 units right and 2 units up
Describe the Transformation FULLY
Rotation 90 degrees counter clockwise
Describe the sequence of transformations from A to B
Reflect over the y-axis and translate 2 units right and 1 unit down
Draw the shape and Label all parts you know measures to.
Will show on whiteboard
