  1. 2. The property of an object or system that remains unchanged under certain transformations, such as reflection, rotation, or translation
  2. 4. (SSS) A postulate in geometry that states two triangles are congruent if all three corresponding sides of one triangle are equal in length to the three corresponding sides of the other triangle
  3. 7. (ASA) A geometric theorem that states two triangles are congruent if two angles and the included side of one triangle are congruent to two angles and the included side of the other triangle
  4. 8. Transformation that moves every point of a figure the same distance in the same direction, essentially sliding the shape without changing its size, orientation, or shape
  5. 10. (SAS) A triangle congruence postulate and an area formula
  6. 12. motion A transformation in geometry that preserves distances, angles, and therefore the size and shape of an object
  7. 13. Exactly equal in size and shape

  1. 1. (HL) A geometry postulate that proves two right triangles are congruent if their hypotenuses are congruent and their legs are congruent
  2. 3. A transformation that creates a mirror image of a figure across a line or plane
  3. 5. Two figures are similar if they have the same shape but not necessarily the same size
  4. 6. (AAS) Two triangles are congruent if two of their corresponding angles and a non-included side are equal
  5. 9. A transformation that turns a figure around a fixed point called the center of rotation by a specified angle and direction
  6. 11. A mathematical transformation, also known as a rigid motion or congruence transformation, that preserves distances between points and thus preserves the size and shape of figures
