Document Summary
Over 90 degrees a line segment connecting two non-adjacent vertices following in order. A parallelogram with four congruent sides quadrilateral with four right angles. A line who"s both endpoints lie on a circle. A line touching only two points on a circle and goes through the midpoint. A line that crosses a circle only once. Starts from statements accepted as true and applied to a new situation a(n) = (n + n) a(n) = n a(n) = (3n - n) a(n) = 2n - n. Angles opposite one another at the intersection of two lines. Two adjacent angles whose sum is 180 degrees. Congruence shortcuts whose middle term is in between the other two. A line that is perpendicular to a segment, and is on its midpoint. 2. from one endpoint, make a circle that passes through the other endpoint. 3. without changing the set of the compass, repeat using the other endpoint. 4. connect the two points where the circles cross.
