Down: 1) A plane figure with four equal straight sides and four right angles.3) A straight line which links two points without extending beyond them. 4) A polygon where all sides are all of the same length and its angles are the same size. A square is a great "regular" example!5) A flat (2 dimensional) closed figure. IIt is made up of three or more line segments (sides) that connect end to end.6) A four-sided polygon. 7) A polygon that does not have all sides equal and all angles equal.10) A six sided polygon.11) shapes that the only difference is size (and possibly the need to turn or flip one around. Otherwise they are exactly alike.14) One of the angles of the triangle measures more than 90 degrees15) A four-sided polygon with two pairs of parallel sides.16) A triangle having two sides of equal length. 18) If one shape can become another using Turns, Flips and/or Slides, then the two shapes are called ________?20) A figure that can be traced with the same starting and stopping points, and without crossing or retracing any part of the figure. There are no openings in this figure. Polygons are a great example of these!22) The angles all measure less that 90 degrees.24) straight line which passes through the center of a circle.25) A shape that has a radius, circumference and a diameter. It is NOT a polygon.30) A portion of a line which starts at a point and goes off in one direction to infinity Across: 2) two lines across from each other that can go on forever with the same equal distance between them. Example: train tracks.8) One of the angles of the triangle measures 90 degrees. 9) Two rays that share the same endpoint (vertex) form an _______________.12) A triangle having three sides of different lengths. 13) A five-sided polygon. 17) An eight sided figure.19) does NOT start and end at the same point. It can't be a polygon because it is not a closed shape.21) A triangle having all three sides of equal length. The angles of an equilateral triangle all measure 60 degrees. Examples: 23) Lines that touch and form a 90 degree angle on eithe side. (example:Picture the steps that connect the parallel lines in a ladder) they can form a "T"26) A line from the center of a circle to a point on the circle.27) A four-sided polygon (a flat shape with straight sides) where every angle is a right angle (90°).Only opposite sides are parallel and of equal length.28) extends forever in both directions.29) The middle part of a circle is called its ________.
