Translations
What is the term for moving an object without rotating or flipping it?
Translation
When a an object is turned around a central, what type of transformation is it?
Rotation
What type of transformation is like folding a figure over a line?
Reflection.
What type of transformation involves changing the size of a figure, but not its shape?
Dilation.
How many degrees are there in a right angle?
90 degrees
In a coordinate grid, if you move a point 4 units to the right and 3 units down, what type of transformation is it?
Translation
If you rotate a figure 90 degrees clockwise, what will its angle measure be after the rotation?
270 degrees
If you reflect a figure over the x-axis, what happens to its y-coordinates?
The y-coordinates change their sign.
If the scale factor of a dilation is 3, what happens to the coordinates of the original figure?
They are multiplied by 3.
What do we call angles that add up to 180 degrees?
Supplementary angles.
What is the mathematical term for the distance and direction of a translation?
Vector
What is the name of the point around which a figure is rotated?
Center of rotation
What is the equation of the line of reflection y = ___?
x-axis.
What is the name of the point around which a figure is dilated?
Center of dilation
What is the term for angles that have the same relative position and measurements but don't necessarily have the same vertex and arms?
Corresponding angles
If a shape is translated vertically 6 units and horizontally 8 units, what is the total displacement of the translation?
10 units
If you rotate an equilateral triangle 120 degrees counterclockwise, how many degrees will each angle of the triangle have after the rotation?
60 degrees
What type of symmetry do figures possess if they have a line of reflection that divides them into matching halves?
Reflectional symmetry
If a shape is dilated by a scale factor of 1221, what happens to its size?
It reduces to half its original size.
What is the name of an angle that measures more than 90 degrees but less than 180 degrees?
Obtuse angle
If a figure is translated 5 units to the right and then reflected over the y-axis, what would be the net effect on the figure?
It's going to end up 5 units to the left of it's original position

Rotational symmetry of order 6
If a figure is reflected over the line y = x, what happens to the x and y coordinates?
They swap places.
What is the term for a dilation with a scale factor of 1?
