Answer:

and Angles: In this chapter students will study the properties of the angle formed when two lines intersect each other and properties of the angle formed when a line intersects two or more parallel lines at distinct points. The chapter starts from zero level, the first topic of the chapter being Basic Terms and Definitions.

Acute angle: Measures between 0°° and 90°°.

Right angle: Exactly equal to 90°°.

Obtuse angle: Angle greater than 90°° but less than 360°°.

Reflex angle: Angle greater than 180°° but less than 360°°.

Two angles whose sum is 90°° are called complementary angles.

Two angles whose sum is 180°° are called supplementary angles. 

Adjacent angles, linear pair of angles and vertically opposite angles are other important topics in this chapter.
