Consider △ABC, where AB=AC=13 units, and m∠BAC=80°. What are the measures of ∠ABC and ∠ACB?
\n" ); document.write( "m∠ABC=__________° and m∠ACD=__________°.
\n" ); document.write( "-------------
\n" ); document.write( "You have an isosceles triangle.
\n" ); document.write( "The vertex angle is 80 deg.
\n" ); document.write( "The 2 base angles are opposite equal sides and therefore equal.
\n" ); document.write( "------
\n" ); document.write( "Each of the base angles is (180-80)/2 = 50 degrees
\n" ); document.write( "m∠ABC= 50° and m∠ACD= 50°.
