translation
is translation a slide, turn, or flip
translation is a slide
is rotation a slide, flip, or turn
rotation is a turn
is reflections a slide, turn , or flip
reflections is a flip
what does congrument mean?
congrument is when you move around the shape but that size of it stays the same.
If your corrdinates start out as (-4, -4), (-2, 2), and (-4, -1) and you SLIDE it 6 units to the right what will your new coordinates be?
your new coordinates will be (2, 4), (4, 2), and (2, -2)
what do translations do?
translation is when the shape slides over the x and y axis
what do rotations do?
rotations turn either clockwise or counter clockwise.
what do reflections do?
reflections is when the shape reflects over the x and y axis
what is the x and y axis?
the x and y axis is a coordinate grid that has two perpendicular lines. the horizontal line is the x axis and the vertical line is the y axis.
if your coordinates start out as (-2, 1), (1, 4), and (3, 2) and you flip over the x axis what will your new coordinates be?
your new coordinates would be (-2, -1), (1, -4), (3, -2)
how do you do translation?
how you translation is you slide the shape across the x and y axis
how do you do rotations?
how you do rotations is you turn the shape over the x and y axis.
how do you do reflections?
how ou do reflections is you mirror the shape over the x and y axis
what is translation?
translation is a term used to describe a function that moved a certain distance. the shape is not altered it just slides to a diffrent spot
if your coordinates start out as (-3, 1), (-1, 4), (-1,0) and you turn your shape clockwise 180 degress what would your coordinates be?
your new coordinates would be (1, -3), (4, -1), (0, -1)
what is the rule of translation?
the rule of translation is a mapping rule of the form (x,y) to (x, -7, y+5)
what is the rule of rotation?
the general rule for rotation of an object 90 degrees is x,y to -y,x. the rule for the other common degree rotations are for 180 degrees, the rule is x,y to -x,-y
what is the rule for reflections?
The rule for the reflection around the Y axis is you basically just put a "negative" in front of the X coordinates of each point. If a point is, say, 2 units away from the Y axis in the positive direction, its reflection across the Y axis would be 2 units from the Y axis in the negative direction. In this case
what is rotation?
rotation is when you TURN the shape clockwise or counter clockwise
if your coordinates start out as (1,3), (5,2), (4,-1) and you reflect it over the the y axis what would your new coordinates be
your new coordinates would be (-1,3), (-5,2), (-4,-1)
what is reflection
reflection is when you mirror the shpae over the x and y axis
if your coordinates start out as (-5,3), (-5,-2), (-3,1) and you reflect it 2 units ti the right what would your new coordinates be?
your new coordinates would be (1,3), (1,-2), (-1,1)
