Answer:
Step-by-step explanation:
Triangle A has 3 vertices. We'll call them B, C and D, with B(1,1), C(4,1) and D(4,3). Since this triangle is in the first quadrant and we are reflecting (which is basically flipping) it over the x-axis, it will be located in the 4th quadrant, meaning the x-coordinate of the points will be positive, and the y-coordinate will be negative. This means that a point with coordinates (x,y) will have the new coordinates (x,-y) after being reflected. Following this, you will have a triangle with coordinates (1,-1), (4,-1) and (4,-3). Hope this helps!
