Same Side Interior Angles And Same Side Exterior Angles. Similar to before angles 1 2 7 and 8 are EXTERIOR angles. If all three sides of one triangle are congruent to three corresponding sides of another triangle the triangles are congruent.
Same side interior and same side exterior. The same side interior angles are the angles inside the parallel lines on the same side of the transversal and the same side exterior angles are the angles outside the parallel lines on the same side of the transversal. Also like with interior angles the above exterior angles are equal when a transversal line crosses 2 parallel lines.
Therefore m1 m2 m4.
Same Side Interior Angles are two angles that are on the same side of the transversal and on the interior of between the two lines. You will explore same-side interior and same-side exterior angle pairs when parallel lines are cut by a transversal. We know that same side interior angles are supplementary so their measures add up to 180. Also like with interior angles the above exterior angles are equal when a transversal line crosses 2 parallel lines.
