If you have three squares each having an area of 10 cm^2, they form a triangle by touching corners what is the area of the triangle
\n" ); document.write( ":
\n" ); document.write( " $\"sqrt%2810%29\"$ = the side of the square and the sides of the equilateral triangles formed by the 3 squares
\n" ); document.write( ":
\n" ); document.write( "Find the altitude of the triangle, (a)
\n" ); document.write( "This is an equilateral triangle all angles = 60 degrees
\n" ); document.write( "Use the sine of 60 to find the altitude
\n" ); document.write( "sin(60) = $\"a%2Fsqrt%2810%29\"$
\n" ); document.write( "a = 2.74 is the altitude of the triangle
\n" ); document.write( "A = $\"1%2F2\"$ * $\"sqrt%2810%29+%2A+2.74\"$
\n" ); document.write( "A = 4.33 sq/cm \n" ); document.write( "

\n" );
