Corresponding Angles<\/h3>\n\n\n\n<p>When a transversal intersects two parallel lines, corresponding angles are formed in matching corners on each line. For example, if angle 1 is in the upper right corner of one intersection and angle 2 is in the upper right corner of the other intersection, then angle 1 is congruent to angle 2. This congruence occurs because both angles occupy the same relative position to the transversal and the parallel lines.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Alternate Exterior Angles<\/h3>\n\n\n\n<p>Alternate exterior angles are the pairs of angles that lie outside the two parallel lines but on opposite sides of the transversal. For example, if angle 3 is located outside of the first line and angle 4 is outside of the second line on the opposite side of the transversal, angle 3 and angle 4 are congruent when the lines are parallel.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Vertical Angles<\/h3>\n\n\n\n<p>Vertical angles are formed when two lines intersect, creating pairs of opposite angles. For instance, if two lines intersect and create angles 5 and 6, those angles are always congruent because they are formed by the same two lines.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Alternate Interior Angles<\/h3>\n\n\n\n<p>Similar to alternate exterior angles, alternate interior angles are formed on opposite sides of the transversal but inside the parallel lines. If angle 7 is on one side of the transversal and angle 8 is directly across from it on the other side, then angle 7 and angle 8 are congruent when the lines are parallel.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Not Congruent Angles<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Same Side Exterior Angles<\/strong> and <strong>Same Side Interior Angles<\/strong> are never congruent; instead, they are supplementary (their measures add up to 180 degrees).<\/li>\n\n\n\n<li><strong>Linear Pair Angles<\/strong> are also not congruent; they are adjacent angles that sum to 180 degrees but do not necessarily have equal measures.<\/li>\n<\/ul>\n\n\n\n<p>In conclusion, the angles that are always congruent when lines are parallel are <strong>corresponding angles, alternate exterior angles, vertical angles<\/strong>, and <strong>alternate interior angles<\/strong>. Understanding these relationships is crucial for solving problems involving angle measures in geometric configurations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which pairs of angles are always congruent?
