Across
A(n) ________ changes the size of an object through an enlargement or reduction.
If the degree of rotation is something other than 90°, 180°, 270°, or 360°, you must use a(n) __________.
In regular polygons, if n is even, there are two scenarios: 1. The lines of symmetry will pass through opposite ________.
A(n) ___________ slides the shape in any direction.
This polygon has all angles and sides of the polygon are congruent.
A rotation changes the ________ of a figure by moving it around a fixed point to the right (clockwise) or to the left (counterclockwise).
"____-" means 'many'
"___" means 'sides'
The function R t (x,y) rotates the point (x,y) t° _________________ about the origin.
The sum of the exterior angles of ___ polygon is 360°.
The function R -t (x,y) rotates the point (x,y) -t° _________ about the origin.
The _________ angles of a polygon are the angles on the inside of the polygon formed by each pair of adjacent sides.
When reflecting polygons, the ______ lines are the lines of reflection and a ______ point is the point of reflection.
The pre-figure or pre-image is the ________ object.
The formula to find the ___ of the interior angles of a polygon with 'n' number of sides is (n - 2)180°.
A reflection is a mirrored version of an object. The image does not change size, but the figure itself ________.
In regular polygons, if n is odd, the lines of symmetry will pass through a(n) ______ and the midpoint of the opposite side.
Down
In geometry, _______________ refer to the movements of objects on a coordinate plane.
A non-rigid transformation changes the ____ of the pre-image.
A(n) _____ does not change the size of the pre-image.

This polygon has all angles and sides of the polygon are not congruent.
This polygon has an interior angle greater than 180°.
A(n) ________ turns the shape around a center point.
A(n) ________ angle of a polygon is an angle that forms a linear pair with one of the interior angles of the polygon.
A translation is a rigid transformation that "______" an object a fixed distance in a given direction while preserving the shape and size of the object.
This polygon has one boundary and doesn't cross over itself.
Reflecting a regular n-gon across a line of symmetry carries the n-gon onto ______.
