Vertical angles are always adjacent. truefalse

Hello! this is  false.  vertical angles are directly across from one another, and have the same measurements. complementary/supplementary angles are always adjacent, with complementary angles totalling 90° and forming a right angle, and  supplementary angles totalling 180° and forming a straight line.hope i ! : 3

That is "false" because vertical angles are always congruent and never adjacent. they measure equally but in opposite directions from each other. that is also why vertical angles have second name called opposite angles.  let me know if you need further info. : )                - dotz
