The opposite angles are congruent (aka equal) while the adjacent angles are supplementary (they add to 180 degrees).\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "-----------------------------------------------------------------\r \n" ); document.write( "\n" ); document.write( "Problem 2)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "True or false? A right triangle has three angles less than 90°\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "False. By definition, a right triangle has exactly one angle that is 90 degrees. A right angle is a 90 degree angle. So it's impossible to have all three angles less than 90 degrees. An acute triangle is one with three angles less than 90°. \n" ); document.write( " \n" ); document.write( " |
