If there is a correspondence between the vertices of two triangles such that two sides and the included angle of one triangle are congruent to the corresponding sides and angle of the other triangle, then the triangles are congruent under that correspondence. Theorem ...

... measure 120 ) and 6 2 = 6 4 (both measure 60 ). These angles are called vertical angles. Vertical angles are on opposite sides of intersecting lines, and will always be congruent by the Vertical Angles Theorem, which we proved in an earlier chapter. Using this information, you can now deduce the rel ...

... 19. Sample answer: My friend is on the basketball team. She has taken two tests the day after a game and received A’s on both of them. She concluded that she will get an A on any test given the day after a game. This is an incorrect use of inductive reasoning. The fact that the two A tests were take ...
