From the graph coordinates of triangle ABC are A (-5, 4), B (-2, 4) and C (-1, 1). This means that all of the points in the. The co-ordinates of the images of A, B, C reflected in y-axis will be: A. Transformations - Reflect A Triangle Across The Y-Axis mrmaisonet 52.7K subscribers Subscribe 222 38K views 7 years ago This tutorial shows how to reflect a triangle across the. When we reflect a figure over the x-axis, we are essentially flipping the figure over a line parallel to the y-axis. The reflection of point (x, y) across the y-axis is (-x, y). Let A (6, 2), B (3, -1) and C (-2, 4) be the points of a right-angled triangle. The triangle is located directly on top of the y-axis, so part of the triangle is on one side of the y-axis and part.
