Question 3 of 22beginner🔧 ApplyDiagram2 marks
Draw and label an angle with arms ST and SR.
Correct Answer
Draw two rays starting from a common point S. One ray goes through point T (ray ST) and another ray goes through point R (ray SR). Mark the vertex S with a dot. Draw a small curve at the vertex to indicate the angle. Label the angle as TSR or RST, with S as the middle letter since it is the vertex.

Explanation
The chapter explains that to name an angle, 'we use a point on each of the arms together with the vertex to name the angle.' The vertex is always written as the middle letter. In this case, S is the vertex, and the rays ST and SR are the arms of the angle. The angle can be named as TSR or RST.
