When two lines are intersected by a transversal, eight angles are formed. Let us prove, how vertically opposite angles are equal to each other. Decimal. Because b° is vertically opposite 40°, it must also be 40°. � The chapter 5 begins with an introduction to Lines and Angles by explaining the basic concepts of point, line, line segment and angle.Then various types of related angles such as complementary angles, supplementary angles, adjacent angles, linear pair and vertically opposite angles are discussed in detail. Edit. >> << Aligned with IB, Singapore Math, Australian, New Zealand, Canadian, CBSE, ICSE, K12 & other curricula. When two lines intersect, the vertically opposite angles so formed are equal. Alternate angles are the same. Know the congruent properties of vertical angles or vertically opposite angles and apply them to determine unknown angle measures. You're probably wondering why they're called "vertically opposite" angles when they aren't vertical at all.
