Write a symbolic statement of the given compound statement below: 4. If a polygon is not a triangle, then it does not have three sides.

For two triangles to be congruent, it is necessary to have congruent measures of 3 sets of corresponding parts with at least one set being corresponding sides. The three congruency rules are called side-angle-side, angle-side-angle, and side-side-side. Given the two triangles below and the marked corresponding parts, is there enough information to determine if they are congruent? By which rule? Write a congruency statement relating the two triangles.

Mr. Williams had this proof on the board. He asked the class to come up with the reasons to prove each statement is true. Which would not be a reason? Given: Circle A with BAC = DAE Prove: Chord BC = Chord DE B C E D. Statements Reasons 1. Circle A with BAC = 1. ZDAE 2. AB = AC AE = AD 2. |3. ДАВС ДADE 3. 4. Chord BC - Chord DE4.
