Answer:
Option B is correct.
The reflection rule is followed here is, .
Explanation:
Since, the triangle is reflected over the x-axis , then only y- coordinates will get changed but the x coordinates will remain the same.
Therefore, the only reflection rule on the coordinate plane that verifies the triangle are congruent when reflected over x-axis is,
Answer: Quadrant 2
=================================================
Explanation:
Check out the diagram below. An example point in the third quadrant is (-2,-5). This quadrant is the southwest quadrant. Reflect the example point over the x axis (aka the line y = 0) and we get (-2,5). This is shown when we go from point A to point B in the diagram.
The reflection rule is showing that only the y coordinate changes from y to -y. If y is negative, then flip to positive, or vice versa. The x coordinate stays the same.
The point started in quadrant 3 and it moves to quadrant 2 after the reflection over the line y = 0.
Side note: all points on the line y = 0 have a y coordinate of 0
