Vertical Angles Theorem Vertical angles are equal in measure Theorem If two congruent … Theorems include: vertical angles are congruent; when a transversal crosses parallel lines, alternate interior angles are congruent and corresponding angles are congruent; points on a perpendicular bisector of a line segment are exactly those equidistant from the segment’s endpoints. Then … Who Am I? First we need a lemma. When two lines intersect to make an X, angles on opposite sides of the X are called vertical angles. Given: lines a and b are parallel and line c is a transversal. prove: 2 is supplementary to 8 what is the missing reason in the proof?

Gain fluency and confidence in math! Given: lines a and b are parallel and line c is a transversal. If 2 angles are supplementary to the same angle, then they are ≅ Congruent complements theorem. Since congruent angles depend only on the angle measurement, and not on the length of the sides making up the angle, the triangles could be of different sizes and still have congruent … Supplementary angles and complementary angles are defined with respect to the addition of two angles.
