  Directions: Analyze eachfollowing statement involvingvertical angles whethereach statementis true or false.Write EJ if thestatement is true otherwise write EB. 1. Vertical angles are two nonadjacentangles formed by a pair of intersectinglines. 2. Two angles are vertical angles if their sides form two pairs opposite rays. 3. Whentwo lines intersect, they form four pairs of vertical angles. 4. Sometimes thetotal measures of vertical anglesis 180 degrees. 5. Vertical angles have common ray but don’t have common vertex.
