Question

An arc through P and Q and two arcs intersecting at R have been drawn. One arc at R has been drawn from P and the other has been drawn from Q using the same compass setting. QR⎯⎯⎯⎯⎯ and PR⎯⎯⎯⎯⎯ have also been drawn.

Determine the correct justification needed for each statement to prove ∠PAR≅∠QAR.

Answer 1

`\\ \sf\longmapsto AR\cong AR(Common\: side)`

• AR is present in both triangles so it's common

`\\ \sf\longmapsto ∆ARP\cong ∆ARQ(SSS congruence)`

• SSS stands for Side Side Side
• As both triangles are equal so so respective angles are also equal

`\\ \sf\longmapsto <PAR\cong <QAR(\because \triangle PAR\cong \triangle QAR)`
