  1. 5. This angle will always measure less than 90 degrees. It is an angle smaller than a right angle.
  2. 9. These angles are opposite sides from one another. These angles are congruent.
  3. 10. This is the bottom face of figures. Prisms have two of these.
  4. 12. The sum of these angles will always equal 180 degrees. These angles form on a straight angle.
  5. 13. This figure is 360 degrees. Pi is used to find the area and circumference of it.
  6. 16. This triangle's sides are all equal. It will never have different side measures.
  7. 17. This triangle has two equal sides. One side will always be different.
  8. 18. These angles share a common side. Also they share a common vortex.
  9. 20. This triangle's angles are all acute. The angles will never be equal to or greater than 90 degrees.
Down
  1. 1. This angle is more than 90 degrees but less than 180 degrees. It is larger than an cute angle.
  2. 2. This is an intersection of a plane and a solid. It can be vertical, horizontal, or angled,
  3. 3. This angle measures exactly 90 degrees. It is at the intersection of two perpendicular lines,
  4. 4. This angle measures exactly 180 degrees. It changes the direction to point the opposite way.
  5. 6. These figures can be divided into more than one shape. Polygons are an example of this.
  6. 7. This triangle has no equal sides. It looks different from all other triangles.
  7. 8. This happens when two or more figures are equal to one another. Vertical angles are an example of it.
  8. 11. The sum of these angles will always equal 90 degrees. They are usually on a right angle.
  9. 14. This shape is half of a circle. It is formed by cutting a whole circle along a diameter line.
  10. 15. It equals 3.14. Also it can equal 22/7.
  11. 19. This is the distance around a figure. Another word for it is perimeter.
