Question

the graph shows triangles bcd and bcd. which of the following transformations maps bcd onto bcd? translation right 8 units translation right 16 units reflection across the x - axis reflection across the y - axis rotation 90° clockwise around the origin rotation 90° counter - clockwise around the origin rotation 180° around the origin

Explanation:

Step1: Identify transformation type

Check coordinates of B, C, D and B', C', D'.

Step2: Analyze reflection over y-axis

Original (x,y) → (-x,y) for B'C'D'.

Answer:

reflection across the y-axis
