  1. 1. - This term describes when 2 angles and the included side of a triangle are congruent to 2 angles and the included side of another triangle. It is a congruence postulate that is used to prove triangles congruent.
  2. 3. - This term describes when 3 sides of a triangle are congruent to 3 sides of another triangle. It is a congruence postulate that is used to prove triangles congruent.
  3. 7. - A quadrilateral having only one pair of opposite sides parallel. The bases are parallel and the legs are non-parallel sides.
  4. 9. - Right triangle trigonometric function that is used with the adjacent leg value over the hypotenuse value. This is only used on a right triangle.
  5. 10. - This term describes when 2 angles and the non-included side of one triangle are congruent to the 2 angles and non-included side of another triangle. It is a congruence theorem that is used to prove two triangles congruent.
  6. 12. Polygons - Two figures that have congruent corresponding parts such as their matching sides and angles. When naming these, you must list corresponding vertices in the same order.
  7. 14. - Law or rule in Geometry that is common sense and doesn't need to be proven. It is commonly used to prove triangles congruent.
  8. 15. - Right triangle trigonometric function that is used with the opposite leg value over the adjacent leg value. This is only used on a right triangle.
  9. 16. - A parallelogram with four congruent sides and four right angles. It has all parallelogram, rectangle, and rhombus properties.
  10. 18. - A line that intersects a circle at exactly one point. It is perpendicular to the radius at the point of tangency.
  11. 20. - Quadrilateral having two pairs of congruent adjacent sides, but opposite sides aren’t congruent. It has exactly one pair of opposite angles congruent and the diagonals are perpendicular.

  1. 2. - This term describes when 2 sides and the included angle of a triangle are congruent to 2 sides and included angle of another triangle. It is a congruence postulate that is used to prove triangles congruent.
  2. 4. - This term means that the endpoints of the arc are the endpoints of the diameter on a circle. It also measures exactly 180 degrees.
  3. 5. - Used to prove corresponding segments or angles congruent. It is an abbreviation for Corresponding Parts of Congruent Triangles are Congruent.
  4. 6. - When a shape on a coordinate plane is moved clockwise or counterclockwise. The image you begin with is called a preimage.
  5. 8. - A parallelogram that has four congruent sides and perpendicular diagonals Also, each diagonal bisects a pair of opposite angles.
  6. 11. - This divides the segment into two congruent segments. When this happens, the two segments can be set equal to each other to find the value of a variable.
  7. 13. Lines - Coplanar lines that do not intersect. These type of lines have certain relationships such as corresponding angles, alternate interior angles, alternate exterior angles, and same side interior angles.
  8. 17. Arc - An arc that measures more than 180 degrees on a circle but less than 360 degrees. It is found by 360 degrees minus its associated minor arc.
  9. 19. - Right triangle trigonometric function that is used with the opposite leg value over the hypotenuse value. This is only used on a right triangle.
