\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In order for triangles PXQ and PXS to be congruent, angles SPX and QPX must be congruent, which is to say they bisect the right angle vertex P. Construct a segment XY that is parallel to side PS and is perpendicular to PQ, intersecting PQ at Y.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Triangle PXY is then an isosceles right triangle with hypotenuse 1. And therefore segments PY and XY both measure \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now consider triangle QXY which is a right triangle with hypotenuse 2 and leg that measures . From this information and the Pythagorean Theorem, you can calculate the measure of QY.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The measure of the side of the square is PY + QY. Square this value to find the area of your square.\r
