  1. 2. All sides of this triangle are congruent. The angles of the triangle are also congruent.
  2. 3. the slope of a line is the ratio of the amount that y increases as x increases some amount. It is often portrayed as y=mx+b.
  3. 5. A point that is this is lying in the same line as another point. For example, if point A and point B were on the same line they would be _________.
  4. 7. This is a simple quadrilateral with at least two pairs of parallel signs. The opposite or facing sides of this thing are of equal length and the opposite angles of a it are of equal measure
  5. 8. In geometry, it is a statement that is true based on basic geometric principles. These do not require proof but you must have enough evidence to support it.
  6. 12. The meaning of this is having two sides of equal length in a triangle. The following angles are also congruent.
  7. 13. This type of triangle has an angle which is greater than 90 degrees. This also means that the other surrounding angles are less than 90 degrees as they all have to equal to 180.
  8. 14. This side of a triangle is the longest. It is always opposite of the right angle. This side is always equal to the the sum of the squares of the lengths of the other two sides.
  9. 16. In geometry, two figures/angles are this thing if they have the same shape,and size. The figure stays this way even when flipped or move. It is another word that is similar to equal
  10. 17. A _____ is the comparison between two or more quantities.For example, the _____ of apples to lemons could be 2:5.
  11. 18. The _________ is the distance around a circle. To find, 2 x π x radius or π x diameter.
  12. 19. This type of triangle has one angle which is opposite of the hypotenuse at exactly 90 degrees. This would also make two of the sides perpendicular.
  13. 20. These are non-coplanar lines that do not intersect. They are also not parallel.
Down
  1. 1. This is a four-sided figure with straight sides and four angles. There are numerous types of these including parallelogram, rhombus, kite, rectangle, trapezoid,and square
  2. 4. An equation that states two ratios are equal. They can be written as where ratios are expressed as fractions.
  3. 6. This is a line segment joining two verticals of a polygon. It can also be an angle bisector in shapes such as a square and a rectangle.
  4. 7. This term is an exact location in space. It has no dimension.
  5. 9. This is two rays that approach and meet in a corner/endpoint called the vertex. There are three of these in a triangle.
  6. 10. two-dimensional shape with straight sides. For example,triangles, rectangles and pentagons.
  7. 11. This type of triangle with all three angles less than 90 degrees. They still must add up to 180. For example,angle a is 40 degrees, b 75 degrees, and c would be 64 degrees.
  8. 15. This is a method used to find the missing side of a right triangle. The formula for this is A^2+ B^2= C^2 (A and B being the two legs and C as the hypotunuse).
