        ### Curran Bollom

1.       Center of rotation-The point about which a figure is rotated.
2.       Correspondence-The relationship between two or more objects that are matched.
3.       Equilateral triangle-A triangle with three congruent sides.
4.       Image-A figure resulting from a transformation
5.       Isosceles triangle-A triangle with at least two congruent sides.
6.       Parallelogram-A quadrilateral with two pairs of parallel sides.
7.       Plane-A flat surface that extends forever.
8.       Point-An exact location in space.
9.       Polygon-A closed plane figure formed by three or more line segments that intersect only at their endpoints (vertices).
10.      Ray-A part of a line that starts at one endpoint and extends forever.
11.      Regular polygon-A polygon with congruent sides and angles.
12.      Regular tessellation-A tessellation made up of congruent regular polygons.
13.      Rhombus- A parallelogram with all sides congruent.
14.      Rise-The vertical change when the slope of a line is expressed as the ratio Rise/Run or “rise over run.”
15.      Rotational symmetry-A figure has rotational symmetry if it can be rotated less than 360 degrees
around a central point and coincide with the original figure.
16.      Run-The horizontal change when the slope of a line is expressed as the ration Rise/Run or “rise over run.”
17.      Scalene triangle-A triangle with no congruent sides.
18.      Slope-The measure of the steepness of a line on a graph; the rise divided by the run.
19.      Supplementary angles-Two angles whose measures have a sum of 180 degrees.
20.      Tessellation-A repeating pattern of plane figures that completely cover a plane with no gaps or overlaps.
21.      Transformation-A change in the size or position of a figure.
22.      Translation-A movement (slide) of a figure along a straight line.
23.      Transversal-A line that intersects two or more lines.
24.      Trapezoid-A quadrilateral with exactly one pair of parallel sides.
25.      Triangle Sum Theorem-The theorem that states that the measures of the angles in a triangle add up to 180 degrees.

Some of the puzzles that people list for the public get indexed by the search engines (like Google). Some people find those puzzles and cannot figure out how to make a puzzle of their own. So this page now has the navigation sidebar.

There are now buttons on the puzzle so that you can get a clean page, in either HTML or PDF, that you can use your browser's print button to print. The PDF format allows the web site to know how large a printer page is, and the fonts are scaled to fill the page. The PDF takes awhile to generate. Don't panic! Web armoredpenguin.com
