Solution: From the diagram, we have (∠AOC +∠BOE +∠COE) and (∠COE +∠BOD +∠BOE) forms a straight line. So, ∠AOC+∠BOE +∠COE = ∠COE +∠BOD+∠BOE = 180° Now, by putting the values of ∠AOC+∠BOE = 70° and ∠BOD = 40° we get ∠COE = 110°, ∠BOE = 30° and reflex ∠COE = 360o - 110o = 250o. 2. In Fig. 6.14, lines XY and MN intersect at O.
In this chapter, you will study the properties of the angles formed when two lines intersect each other, and also the properties of the angles formed when a line intersects two or more parallel lines at distinct points. Further you will use these properties to prove some statements using deductive reasoning (see Appendix 1).
