Algebra.Com's Answer #105021 by vleith(2983) ![]() You can put this solution on YOUR website! Drop a segment from the vertex at the right triangle down and intersect hypotenuse. What is the measure of both segments on the original hypotenuse? Right it cuts it in half , so they are both 8cm\r \n" ); document.write( "\n" ); document.write( "This results in two new isosceles triangle (they also each are right triangles, with other angles equal to 45).\r \n" ); document.write( "\n" ); document.write( "What do you know about the sides of an isosceles triangle? What can you say about the length of segment you just drew in? Right, that too is 8cm.\r \n" ); document.write( "\n" ); document.write( "So now you have a base of 16cm and a height of 8cm.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
