  1. 4. triangle with right a angles. All interior angles add up to 180.
  2. 7. in which all sides are equivalent. And angles are equal to each other.
  3. 10. when two angles and the non-included side of one triangle are congruent to two angles and the corresponding non-included side of the other triangle. Meaning they are congruent to each other.
  4. 12. case when two shapes lie directly on top of each other. Need to prove shapes congruent first to prove parts congruent.
  5. 13. two sides of a triangle are congruent. Then the angles of the opposite sides are congruent.
  6. 14. geometrical proofs. Are proved to help prove triangles congruent
  7. 15. each pair of opposite angles are made by intersecting lines. They have a common vertex. By this proving triangles congruent.
  8. 19. that if two angles of one triangle are congruent to two angles of another triangle. The third angle has to be congruent
  9. 20. The relationship between the legs and hypotenuse of the right triangle. The sum of the two legs squared is equivalent to the hypotenuse.

  1. 1. angle associated with the vertex of a polygon. Is a interior angle.
  2. 2. when two angles and the included angle of one triangle are congruent to the two angles and the included angles of the other triangle . Thus, proving both triangles congruent to each other.
  3. 3. in which two angles and the included angle of a triangle are congruent to the two sides. Then the two Meaning the two triangles are congruent.
  4. 5. used at the end or near the end of a proof. Useful in proving various theorems about triangles and other polygons.
  5. 6. when three sides of one triangle are congruent to the three sides of another triangle. Then the two
  6. 8. The longest side of a right triangle. Usually opposite to the right angle.
  7. 9. in shape and size. Are equal in length and everything.
  8. 11. The side than the one opposite to the right angle. Is not the hypotenuse.
  9. 16. used at the end or near the end of a proof. Useful in proving various theorems about triangles and other polygons.
  10. 17. two triangles, by using logical explanations. Such as postulates theorems, and other previously proved statements. Thus, coming to conclusive geometrical statements.
  11. 18. the hypotenuse and the leg of one of the right triangle are congruent to the hypotenuse and a leg of another right triangle . The triangles are congruent.
