Here are the solutions for Activity 2:
2.1 Determine, with reasons, the size of:
Given information from the diagram and previous context:
- MN⊥KN⟹∠KNM=90∘.
- PQ∥MK.
- K^=63∘⟹∠MKN=63∘.
- From the diagram, Q^1=Q^2 (indicated by single arcs).
- The line RQ is a straight line.
- P is the intersection of RQ and MK.
- Q is a point on the line PQ.
