1. Question 12 marksGrade 2-3
   Two straight lines intersect. One of the angles formed is $105°$. Work out the size of the vertically opposite angle.
   Show the worked solution

   Vertically opposite angles are equal. M1

   Therefore, the vertically opposite angle = $105°$

What are the common mistakes in Vertically opposite angles?

When a pupil makes one of these on Revision Workshop, the marking engine names the mistake and explains it, instead of just marking the answer wrong.

• Finds an adjacent angle instead of the angle actually asked for

  Found the adjacent angle (supplementary to the vertically opposite) instead

• Uses the expression for a different angle in the diagram instead of the one required

  Calculated the value correctly but reported the angle from the other expression instead

• Uses the adjacent angle instead of the angle actually required

  Found the adjacent angle (which is supplementary, summing to 180°) instead of the vertically opposite angle
