The exterior angles are these same four: ∠ 1 ∠ 2 ∠ 7 ∠ 8; This time, we can use the Alternate Exterior Angles Theorem to state that the alternate exterior angles are congruent: ∠ 1 ≅ ∠ 8 ∠ 2 ≅ ∠ 7 Same-side Exterior Angles Theorem : If a transversal intersects two parallel lines, then same side exterior angles are supplementary. The converse of this theorem is also true; that is, if two lines k and l are cut by a transversal so that the alternate interior angles are congruent, then k ∥ l. cardeiro. X ty ...

We are interested in the Alternate Interior Angle Converse Theorem : If two lines are cut by a transversal and the alternate interior angles are equal (or congruent), then the two lines are parallel. New Resources. A: From the figure, we see that AHUP reflected over the y-axis to form A'H'U'P'. Congruent Supplements Theorem 4. p||q 4. 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.

Converse of Corresponding Angles Theorem. Remember, when parallel lines are cut by a transversal line, same-side exterior angles are formed, which are outside of the parallel lines and on the same side of the transversal line. Theorem 3-6: If same-side interior angles are supplementary then the Same side interior angles are two angles that are on the same side of the transversaland on the interior of (between) the two lines. We are jumping ahead to numbered angles. <4 <8 3. Linear Pair Postulate 3.
