Triangle ABC has vertices A(0, 4), B(2, 1), and C(4, 3). Find the
coordinates of the vertices of ABC after a reflection over the
x-axis.

A3-dimensional figure has a square base and 4 lateral faces that meet at a point. explain the difference between the cross sections when a slice is made perpendicular to the base through the vertex, and when a slice is made perpendicular to the base and not through the vertex
