I wrote my STATEMENTS and REASONS as follows: STATEMENT: 1. Line segments AE & DB intersect at C. REASON: 1. Given. STATEMENT: 2. Line segments AC & EC are congruent. REASON: 2. Given. STATEMENT: 3. Line segments BC & DC are congruent. REASON: 3. Given. STATEMENT: 4. Angles ACB & ECD are congruent. REASON: 4. Vertical angles are congruent (Theorem) VERTICALLY OPPOSITE ANGLES ARE EQUAL..THAT IS THE CORRECT STATEMENT. STATEMENT: 5. Triangles ABC & EDC are congruent. REASON: 5. (SSS are congruent to SSS). If three sides of one triangle are congruent, respectively, to three sides of a second triangle, then the triangles are congruent. (Postualte) ...NO THEOREM IS SAS..2 SIDES AND INCLUDED REPEAT INCLUDED ANGLES ARE EQUAL RESPECTIVELY THE CORRESPONDING SIDES AND INCLUDED ANGLE , THEN THE 2 TRIANGLES ARE CONGRUENT. I'm not sure if Step 4 is correct or if I can even write that statement.IT IS OK BUT FOR THE SLIGHT MODIFICATION SUGGESTED. REASON 5 IS TO BE CHANGED AS GIVEN .
