Answer:
<h2>x = -0.5</h2>
Step-by-step explanation:
Answer:
B. Rotate 180° clockwise around (8, 4) and reflect across the line x=8.
Step-by-step explanation:
The figure is symmetrical (order 2) about the point (8, 4), and about the lines x=8 and y=4.
Hence, rotation 180° about the point (8, 4) makes the figure look unchanged. Since the figure is also symmetrical about the line x=8, reflecting it across that line will also leave the figure unchanged.

Any of the other transformations have the effect of translating the figure somewhere else.
For ΔABD, it is given that side AB is congruent to side CB, that ∠ABD is congruent to ∠CBD. In order to invoke the SAS Postulate, the remaining side(s) fo the triangles must be shown to be congruent. Those sides are BD and BD.
The appropriate choice is ...
... b. BD ≅ BD
