C B A E D $400 Answer Triangle Congruence SAS Return $500 Question Triangle Congruence Why is △ABC≅△ADC? B C D A $500 Answer Triangle Congruence SAS Return $100 Question Congruent Parts What does CPCTC stand for? $100 Answer Congruent Parts Corresponding Parts of Congruent Triangles are Congruent Return $200 Question Congruent Parts △ABC≅△DEF, what is congruent to segment BC? $200 Answer Congruent Parts Segment EF Return $300 Question Congruent Parts △QRS≅△XYZ, what is congruent to angle Q? $300 Answer Congruent Parts Angle X. Return $400 Question Congruent Parts △ABC≅△XYZ, list all of the congruent parts. $400 Answer Congruent Parts Return $500 Question Congruent Parts What must you do before you can say CPCTC? $500 Answer Congruent Parts Prove that the triangles are congruent. Return $100 Question Triangle Reasoning Can you have 2 obtuse angles in a triangle? Explain why or why not. $100 Answer Triangle Reasoning No, because that would means 2 angles greater than 90 which already adds up to over 180°. Return $200 Question Triangle Reasoning What must be true about the angles in a scalene triangle? $200 Answer Triangle Reasoning They must all be different because all of the sides are different and only equal sides can have equal opposite angles. Return $300 Question Triangle Reasoning Is it possible to have a right obtuse triangle? Why or why not? $300 Answer Triangle Reasoning No, because that would create an angle sum of more than 180°. Return $400 Question Triangle Reasoning Why is SSA not enough to prove triangles congruent? $400 Answer Triangle Reasoning Because SSA leaves two options for a triangle. An acute option and an obtuse option. Return $500 Question Triangle Reasoning Explain why an exterior angle is the sum of the other interior angles. $500 Answer Triangle Reasoning Because both the exterior angle and the sum of the other two angles are supplementary to the third interior angle. Return $100 Question Odds and Ends Write an equation that passes through the points (3, 2) and (5, 6). $100 Answer Odds and Ends y=2x-4 Return $200 Question Odds and Ends Name a pair of congruent angles. $200 Answer Odds and Ends Vertical Angles Corresponding Angles Alternate Interior Angles Alternate Exterior Angles Return $300 Question Odds and Ends What type of statement includes “iff”? $300 Answer Odds and Ends A bi-conditional statement. Return $400 Question Odds and Ends What is the difference between a segment, ray and line? $400 Answer Odds and Ends A segment has a definite length, a ray extends in one direction, and a line extends in both directions Return $500 Question Odds and Ends Write the converse of the following statement. If you answer this question correctly, then you will get 500 points. $500 Answer Odds and Ends If you get 500 points, then you answered this question correctly.
