isosceles triangle. How long would the cloth have to so that the opening of the tent was 4 meters high and 3 meters wide?\r
\n" ); document.write( "\n" ); document.write( "Draw the picture and imagine the open door is being
\n" ); document.write( "held up by a pole.
\n" ); document.write( "The pole is the altitute of the isosceles triangle.
\n" ); document.write( "Do you see the two fight angles formed at the base of
\n" ); document.write( "the pole?
\n" ); document.write( "Now do you see the two right triangles that are formed?
\n" ); document.write( "Use Pythagoras to find 1/2 the length of the cloth, as follows:
\n" ); document.write( "cloth^2 = base^2 + altitude^2
\n" ); document.write( "c^2 = (3/2)^2 + 4^2
\n" ); document.write( "c^2 = 9/4 +64/4= 73/4
\n" ); document.write( "c= (1/2)sqrt(73) (that's the length of 1/2 the cloth
\n" ); document.write( "2c= sqrt(73) meters (that's the length of the whole cloth
