label: Description
content: This tan paper model shows the intersection of two triangles with a plane. One is a vertical right tiangle, perpendictular to the plane. The other rests on the hypotenuse of the first triangle. Drawn on the second triangle is a line that is perpendicular to a line on the base. A mark on the model reads: L(. . .)PL-L (. . .) L*. Here the characters (. . .) represent the symbol for perpendicular.
