Construction 2: To construct an angle congruent to a given angle Given: ZA To construct: An angle congruent to Z A Construction: With A as center and a convenient radius, construct an arc (1) intersecting the sides of A and B and C. With A', a point on a working line w, as center and the same radius, construct arc (2) intersecting w at B' as center and a radius equal to BC, construct arc (3) intersecting arc (2) at C'. Draw A'C'. Then <A' is the required angle. (AABC= AA'B'C' by s.s.s.s.S.S.; hence ZA ZA'.) Explanation ZA ZA since AABCAA'B'C' by s.s.s. and c.p.t.c.
