The answer is b hope this helps
A rigid transformation <span>is a transformation of the plane that preserves length. In a rigid transformation the initial shape and the image shape are congruent.
</span>
Main properties:
<span>1. distance (lengths of segments remain the same)
</span><span>2. angle measures (remain the same)</span><span>
</span><span>
3. parallelism (parallel lines remain parallel)</span><span>
</span><span>
4. collinearity (points remain on the same lines)</span><span>
</span><span>
5. orientation (lettering order remains the same)
</span><span>
</span><span>Taking these properties into account, the correct choice is C.</span>
Step-by-step explanation:
z = 0 -7i ....................
Only one because the angles must add up to 180 degrees
The value of y is a number equal to 3
