Translations
What is a translation in math?
what are Rotations?
the action of rotating or turning around an axis or center.
what is the meaning of reflection?
A reflection is a mirror image of the shape.
how do you find dilation?
What are 4 types of angles in math?
The names of basic angles are Acute angle, Obtuse angle, Right angle, and Straight angle.
How can you translate a point or figure in math?
In the coordinate plane we can draw the translation if we know the direction and how far the figure should be moved. To translate the point P(x,y) , a units right and b units up, use P'(x+a,y+b) .
What is the 90 rotation rule?
90° clockwise rotation: (x,y) becomes (y,-x) 90° counterclockwise rotation: (x,y) becomes (-y,x)
How does reflection work?
A figure is said to reflect the other figure, and then every point in a figure is equidistant from each corresponding point in another figure across the line of reflection.
Does dilation change orientation?
A dilation is a transformation that preserves the shape and orientation of the figure but changes its size.
what is an angle?
An angle is formed when two straight lines or rays meet at a common endpoint.
What is a translation problem on the coordinate plane in math?
A translation in math moves a shape left or right and/or up or down.
What are the 4 types of rotation?
Rotation of 90° (Clockwise) (x, y)(y, -x)
Rotation of 90° (Counter Clockwise)(x, y)(-y, x)
Rotation of 180° (Both Clockwise and Counterclockwise)(x, y)(-x, -y)
Rotation of 270° (Clockwise) (x, y)(-y, x)
What happens when you reflect something?
The image is congruent to the preimage.
Does dilation preserve distance?
Dilations do not preserve distance.
What makes an angle A angle?
When two straight lines or rays meet at a common endpoint.
What is the translation rule for a figure?
A translation is a type of transformation that moves each point in a figure the same distance in the same direction.
Do rotations preserve or change the orientation of the vertices?
It is preserved during these transformations: translations, dilations, and rotations.
how do you reflect y=x?
When reflecting over the line y=x, we switch our x and y.
What is the rule of dilation?
A dilation is a type of transformation that enlarges or reduces(shrinks) a figure (called the preimage) to create a new figure (called the image). The scale factor determines how much bigger or smaller the dilation image will be compared to the preimage.
How many letters make an angle?
Three letters.
What is the point of the translation?
The transformation that simply moves a shape or point a certain distance in a specific direction without changing its size or shape, essentially "sliding" it across a plane.
How do rotations work?
A rotation is a transformation that turns a figure about a fixed point called the center of rotation.
What are the rules for reflection?
Ordered pair rules reflect over the x-axis: (x, -y), y-axis: (-x, y), line y=x: (y, x).
What does it mean to dilation?
Dilation is a transformation, which is used to resize the object.
Which tool is used to measure an angle?
