Consecutive interior angles are defined as the pair of non-adjacent interior angles that lie on the same side of the transversal. The word 'consecutive' refers to things that appear next to each other. Consecutive interior angles are located next to each other on the internal side of a transversal The Fire Station and the Worship Center lie on the same side of the transversal and form a linear pair. The Museum and the Coffee Shop lie on the opposite sides of the transversal and form a pair of alternate exterior angles. The Bank, the Museum, the Coffee Shop, the Worship Center are interior angles
Naming Angle Pairs Formed by Parallel Lines Cut by a Transversal. With this bunch of image-based exercises, students get to recognize vertical, linear, corresponding, same-side, and alternate pairs of angles by analyzing the position and size of the angles depicted Converse to the Same-side Exterior Angles Theorem : If two lines and a transversal form same-side exterior angles that are supplementary, then the two lines are parallel.

If two lines are parallel then the interior angles on the same side of the transversal are supplementary (they add uP to \(180^{\circ}\)). If the interior angles of two lines on the same side of the transversal are supplementary then the lines must be parallel This is an old idea about angles revisited. Since a straight angle contains 180Â°, these two adjacent angles add to 180. They form a linear pair. (Adjacent angles share a vertex, share a side, and do not overlap.) Theorem: If two angles form a linear pair, they are supplementary Corresponding angles \(\angle\)a is an exterior and\(\angle\)d is an interior angle lying to the same side of the transversal and they are not adjacent to each other.; They are called corresponding angles. b and d are another pairs of corresponding angles. A pair of corresponding angles made by a transversal with parallel lines is always equal All angles that have the same position with regards to the parallel lines and the transversal are corresponding pairs e.g. 3 + 7, 4 + 8 and 2 + 6. Angles that are in the area between the parallel lines like angle 2 and 8 above are called interior angles whereas the angles that are on the outside of the two parallel lines like 1 and 6 are called. Pairs of Angles. When parallel lines get crossed by another line (which is called a Transversal), you can see that many angles are the same, as in this example:. These angles can be made into pairs of angles which have special names
The angle between two sides of a polygon is an interior angle, whereas the angle formed by one side and extending the other side of an angle in a polygon is an exterior angle. They form a linear pair. Examples of interior angles would be those labelled x and 60 Âº in the figure left. The angle labelled (2x+4) Âº is an exterior angle. We can also differentiate between the interior and exterior. The angle marked with measure 53Â° and âˆ 8 are alternate exterior angles. They are in the exterior, on opposite sides of the transversal. Because they are congruent, the measure of âˆ 8 = 53Â°. Example: What is the measure of âˆ 7? âˆ 8 and âˆ 7 are a linear pair; they are supplementary. Their measures add up to 180Â° Solution 2: By corresponding angles theorem, angles on the transversal line are corresponding angles which are equal. Thus exterior âˆ 110 degrees is equal to alternate exterior i.e. 110 degrees. X is adjacent. Making a semi-circle, the total area of angle measures 180 degrees. Thus. 110 +x = 180. X = 180 - 110.
