What are the four kinds of symmetry?
Rotation: move the object around the plane. Each rotation has a center and an angle.Translation: move the object on the plane without rotating or reflecting it. Each translation has a direction and distance.Reflection: mirror image of the object. Always has a mirror line.Glide Reflection: combination of a reflection and translation along the mirror line.
What does translation means in math terms?
It means moving an object or a line on a graph to a different place, without twisting or turning it.
How does the distance of the object compare with the distance of the image from the plane mirror?
The distance of the object from the mirror line should equal the distance of the image from the mirror line.
Describe the ideas of point line and plane?
A point is a coordinate on an axis. A line is the connection between two points. A plane is the object of perspective that points and lines lie on.
What is the angle between a plane mirror and the straight line joining the object and its image?
90 degrees (That line is the normal to the mirror.)
To slide or move a figure to a new position along a straight line?
to slide or move a figure to a new position along a striaght line

What is the speed and direction of any object?
Along a straight line
What is the intersection of a cone and a plane parallel to a line along the side of a cone?
a parabola

90 degrees (That line is the normal to the mirror.)
What geometric object occupy one dimension Line Plane Ray Triangle Segment Point?
Line, Ray and segment
Which geometric object is defined as the set of all points in a plane that are equidistant from a point and a line?
parabola
Does the origin of an object always have to be at a zero on a number line or X-y plane?
always on 0.
