TRUE
Under the translation (x,y,) -> (x+3,y+2) the point (2,5) will become (5,7).
100
A transformation in which a geometric figure is reflected across a line, creating a mirror image. That line is called the axis of reflection.
What is the definitions of reflections?

Rotation in mathematics is a concept originating in geometry. Any rotation is a motion of a certain space that preserves at least one point. It can describe, for example, the motion of a rigid body around a fixed point.
What is the definition of rotation?
100
if its image is itself in 180 degrees or less
What is rotaional symmetry?
100
A change in position, in size, and in shape.
What is a transformation?

False
Under the translation T (-1,2) the point (-2,3) will become (-3,1).
200
Preimage and image have an opposite orientation

What is a preimage
300
False. Real answer is (1,9).
Under a translation of 5 units up and 2 units to the left, the point (3,4) will become (8,6).

What is the new points from ABC to A1B1C1 across the x-axis
300
5 lines
How many lines of rotation does a pentagon have?
300
Both rotational and reflectional
What type of symmetry is an umbrella top?
300
Preimage and the image are congruent or identical in form.
What is isometry?
400
(x, y) → (x + 4, y + 2)
What is the mathematical notion shown below (drawing on seperate piece of paper)
400
The line in between the new image and old image
What is the line of reflection?
400
"Rotation" means turning around a center: The distance from the center to any point on the shape stays the same.
What does rotation mean?
400
YES
Is it possible for a figure to have more than one line of symmetry?
400
It's image is exactly 180 degrees
What is point symmetry?
500
Translation is a term used in geometry to describe a function that moves an object a certain distance. The object is not altered in any other way. It is not rotated, reflected or re-sized. In a translation, every point of the object must be moved in the same direction and for the same distance.
What is the definition of translation
500
Equal distance
If a point is NOT on the line of reflection, then the point and its image are _____ from the line of reflection?
500
Option A Option B Option C Option D
If you rotate a square half of a complete turn from the points that are shown in the picture what would the new square look like
500
Symmetry means that one shape becomes exactly like another when you move it in some way: turn, flip or slide. For two objects to be symmetrical, they must be the same size and shape, with one object having a different orientation from the first. There can also be symmetry in one object, such as a face.
What is the definition of symmetry?
500
Reflectional
