In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid.
Since the two lines are parallel, the corresponding angles are equal. a and e are corresponding angles. b and f are corresponding angles. c and g are corresponding angles. d and h are corresponding angles. As Shown below, there are also two pairs of alternate interior angles and two pairs of alternate exterior angles.

Proving Lines Parallel. About this worksheet. In this worksheet, students complete two geometry proofs. In each proof, students must prove that two lines cut by a transversal are parallel.
In the following example assuming two lines are not parallel gives us a triangle to work with that wasn't obvious in the original statement of the problem. Example: Theorem: If two lines are cut by a transversal so that the alternate interior angles are equal, then the lines are parallel. This theorem does not depend on the parallel postulate.

If two lines form congruent adjacent angles, then they are perpendicular. If the exterior sides of two acute adjacent angles are perpendicular, then the angles are complementary. Students are then asked to state the definition, postulate, or theorem that justifies given statements, using ideas going back to the beginning of the Geometry course.

What are Parallel and Perpendicular Lines? - We see lines going in different directions, don't we? Sometimes they're going upwards, downwards, straight Parallel lines - Have you seen how the railway tracks run on the ground? They are quite apart from each other and seem like they never meet.
SUMMARY: The side-splitter theorem states that if a line is parallel to one side of a triangle and intersects the other two sides, then it divides those sides proportionally. A corollary to this theorem states that if three parallel lines intersect two transversals, then the segments intercepted on the transversals are proportional.
