If two lines are intersected by a transversal and the same-side interior angles are supplementary then, the lines are parallel. Theorem: In a plane, if two lines are perpendicular to the same line then the lines are parallel. Theorem: Through a point not on the line, there is exactly one line parallel to the given line. Theorem: Through a point ...

Mathematicians Reconsider Euclid's Parallel Postulate Overview. Ever since the time of Euclid, mathematicians have felt that Euclid's fifth postulate, which lets only one straight line be drawn through a given point parallel to a given line, was a somewhat unnatural addition to the other, more intuitively appealing, postulates.

And as we read right here, yes it is. If two lines and a transversal form alternate interior angles, notice I abbreviated it, so if these alternate interior angles are congruent, that is enough to say that these two lines must be parallel.

You need to find a slope that would be perpendicular to -9, so flip it and change sign to get 1/9. Then plug in that slope and the point (-1, 7) into the point slope form (y – y1) = m(x – x1) ( y – 7) = 1/9(x - -1) (y – 7) =.
When two parallel lines are given in a figure, there are two main areas: the interior and the exterior. When two parallel lines are cut by a third line, the third line is called the transversal . In the example below, eight angles are formed when parallel lines m and n are cut by a transversal line, t.

Earl and Sean provide the following proofs for vertical angles to be equal. Earl’s proof: angle 1 + angle 2 = 180° (PQ is a straight line) angle 3 + angle 4 = 180°(PQ is a straight line) Therefore, angle 1 + angle 2 = angle 3 + angle 4 Hence, vertical angles are equal. Sean’s proof: angle 1 + angle 4 = 180° (transversal t is a straight line)
Given that a straight line passes through the point P(3,2,1). This implies that the required line has direction ratios as (0,-4,2). Hence in cartesian form we can represent the line as.
