  1. Beat the Computer! Geometry Vocabulary for Congruent Triangles

  2. Directions: • Study definitions for your oral quiz • Say the definition aloud • Summarize the activity and bring it to class with your name. • You can e-mail me or see me.

  3. congruent polygons

  4. congruent polygons: are polygons with congruent corresponding parts - their matching sides and angles B Y A X C Z D W Polygon ABCD  Polygon XYZW

  5. SSS Side-Side-Side Postulate

  6. SSS If three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent. H Q G P F R  GHF   PQR

  7. SAS Side-Angle-Side Postulate

  8. SAS If two sides and included angle of one triangle are congruent to two sides and included angleof another triangle, then the two triangles are congruent. B D C F A E  BCA   FDE

  9. ASA Angle-Side-Angle Postulate

  10. ASA If two angles and included side of one triangle are congruent to two sides and included angleof another triangle, then the two triangles are congruent. B P G K H N  HGB   NKP

  11. AAS Angle-Angle-Side Postulate

  12. AAS If two angles and nonincluded side of one triangle are congruent to two angles and nonincluded side of another triangle, then the two triangles are congruent. pg. 195 C T D G M X  CDM   TGX

  13. CPCTC Chris Giovanello, LBUSD Math Curriculum Office, 2004

  14. CPCTC: corresponding parts of congruent triangles are congruent

  15. legs of an isosceles triangle

  16. legs of an isosceles triangle: the congruent sides of an isosceles triangle Legs

  17. base of an isosceles triangle

  18. pg211 base of an isosceles triangle: the side of an isosceles triangle that is not congruent to either of the other sides Base

  19. vertex angle of an isosceles triangle

  20. vertex angle of an isosceles triangle: the angle formed by the two congruent sides of an isosceles triangle Vertex Angle

  21. base angles of an isosceles triangle

  22. pg. 211 base angles of an isosceles triangle: the angles opposite the congruent sides of an isosceles triangle Base Angles

  23. corollary

  24. pg. 212 corollary: a statement that follows immediately from a theorem

  25. hypotenuse of a right triangle

  26. pg. 217 hypotenuse of a right triangle: the side opposite the right angle Hypotenuse

  27. legs of a right triangle

  28. legs of a right triangle: the sides that are not opposite the right angle Legs
