PQ and QR are 2 sides of a regular polygon. PR is a diagonal of the polygon.
Work out the size of angle PQR?
回答 (2)
PQ and QR are adjacent sides, and PR is a diagonal.
Hence, the regular polygon has 4 sides.
In other word, it is a square.
Each interior angle of a square is 90°.
Hence, ∠PQR = 90°
PQ and QR are °2 sides of a regular polygon.
PR is a diagonal of the polygon.
The polygon is a square.
∠PQR = 90°
