Algebra.Com's Answer #644625 by LinnW(1048)![]() ![]() You can put this solution on YOUR website! Since D is the midpoint of of AC, AD = DC \n" ); document.write( "Since BED is a perpendicular, angle ADB and angle CDB are each right angles \n" ); document.write( "By SAS, Side Angle Side, we know triangle ADE is congruent to triangle CDE, \n" ); document.write( "where AD = DC, angle ADB = CDB and DE = DE since the lines are coincident. \n" ); document.write( "Since the triangles are congruent, AE = EC \n" ); document.write( " |
