  1. 1. A two dimensional geometric figure. It possesses four sides and four angles.
  2. 3. The chance of an event occurring. In geometry, it is the likelihood that you will hit a particular area of a figure.
  3. 4. What shapes are referred to as if they have the same size and shape. The shapes can be translated on top of each other and match up perfectly.
  4. 5. Refers to things that exist on the same plane. Is commonly used to refer to sides of a shape or lines.
  5. 10. The longest side of a right triangle. It is located opposite to the right angle.
  6. 11. This is a uniform, three dimensional shape. It possesses 20 vertices, 30 edges, and 12 faces.
  7. 13. This is a smooth curve that joins two points. Its length can be found by multiplying the circumference by the ratio of the central angle to 360 (2πr[x/360])
  8. 14. A straight line that runs from one side of a figure to the other, passing through the center. Is also known as the longest chord in a circle.
  9. 16. Shapes are described as this when they share characteristics, but are not identical. These shapes can be made congruent by a rotation, translation, dilation, and/or reflection.
  10. 17. A branch of mathematics that is focused on the relationships and properties of different formations. These formations include, but are not limited to, points, lines, line segments, and shapes.
  11. 18. The distance around the edge of a circle. Is found by solving the expression 2πr, where r is radius.

  1. 2. A shape with three straight sides and three straight angles. The interior angle sum adds to be 180.
  2. 4. The set of every point in a plane that is a fixed distance from a point. The interval joining a point on the plane and the center is known as a radius.
  3. 6. A flat surface that has an infinite area. All two dimensional shapes are on one of these.
  4. 7. A diagram that can be used to plot various two dimensional structures. These include points, lines, line segments, and various shapes.
  5. 8. A line segment joining two points in a curve. This is often used to describe a segment within a circle.
  6. 9. Has two sides that are equal in length. Also has two angles that are equal in length.
  7. 11. A measurement of a plane angle in which one full rotation is 360. Is denoted by a small super-scripted circle.
  8. 12. A comparison between values. This is often written in fractional form.
  9. 15. the point on a line segment or arc that is equidistant from both endpoints. When said line segment or arc is bisected, this is where the bisector cuts.
