Therefore, angles 2 and 7 are the pair of alternate exterior angles. There are 2 types of alternate angles depending on the position of angles with respect to the transversal. Remember: interior means inside the parallel lines. When the interior angles are on opposite sides of the transversal, they are alternate interior angles.

The smaller segment is known as the minor segment while the larger one is known as the major segment. We identified it from trustworthy source. Alternate segment theorem If a line touches a circle and from the point of contact a chord is drawn, then the angles that this chord makes with the given line are equal to the angles formed in the corresponding alternate segments, respectively. The angle between a tangent and chord is the same as the angle in the alternate segment. Angles are categorized into four types: complementary, supplementary, vertical, and adjacent. The theorem states that in a circle, the angle which lies between the chord and tangent passing through the end points is equal to the angle in the alternate segment. True/False - If the angle formed between a line, that is drawn through the end point of a chord, and the chord, is equal to the angle subtended by the chord in the alternate segment True/False - A portion of the line formed with two definite points is called a Line Segment.
