Answer:
Step-by-step explanation:
Adjacent angles, linear pair of angles and vertically opposite angles are other important topics in this chapter.
Section 6.3 is about the topic- Intersecting Lines and Non-Intersecting Lines.
If two lines intersect each other, then the vertically opposite angles are equal.
After that, the topic- Pair of Angles is discussed. 2 axioms, 1 theorem, and some solved examples are also given in this section.
Axiom 6.1 states about linear pair of angles.
Linear pair axiom is discussed.
Exercise 6.1 contains various questions based on all the concepts discussed in the section.
The next section is about Parallel Lines and a Transversal. Axioms and theorems about this concept are explained.
Lines that are parallel to a given line are parallel to each other.
Corresponding angles axiom is also discussed.
Theorem on alternate interior angles is also given in this chapter.
Moving on, students will find a detailed description of Lines parallel to the Same Line. Exercise 6.2 contains 6 questions.
Lines parallel to the same line is discussed with the help of corresponding angles axiom.
Then chapter will also lay emphasis on Angle Sum Property.
The sum of the three angles of a triangle is 180°.
Exterior angle of a triangle is greater than the sum of the interior opposite angles.
Theorem and examples are given in this section. After that, another unsolved exercise i.e 6.3 is given.
In the end, a summary of the chapter is provided.
