Are parallel triangles similar?
Space and AstronomyWhen a line is drawn parallel to one side in a triangle, two similar triangles are formed because corresponding angles yield the AA similarity shortcut. Because the triangles are similar, the segments formed by the parallel line are proportional segments. What is a parallel triangle? Geometry. If a line parallel to one side of a
