The document provides instructions for preparing a slide: 1) Draw line AB and line AC to form a triangle on a flat surface. Mark the points where the lines intersect as P and Q. 2) Draw lines from P and Q perpendicular to AB. Label the point where the lines intersect as S. 3) Connect points B and S with a line, forming triangle ABS. This will be the slide.
