A triangle ABC with vertices A (2, 5), B (5, - 2) and C (0, -1) is reflected along the y-axis to give the image triangle A/B/C/.
The coordinates of the vertices of A/B/C/ are:
A/(-2, 5) , B/(5,2) , C/(0, 1).
A/(-2, 5) , B/(-5,2) , C/(0, 1).
A/(2, 5) , B/(-5,2) , C/(0, 1).
A/(-2, 5) , B/(-5,-2) , C/(0, -1).
The figure is a circle with centre O and a chord PQ subtending an angle of 70° at the centre, O.
The value of the angle marked θ is:
20°.
55°.
70°.
