      4-4 Congruent Triangles Geometric figures are congruent if they are the same size and shape. Corresponding angles and corresponding sides are in the same position in polygons with an equal number of sides. Two polygons are congruent polygons if and only if their corresponding sides are congruent. Thus triangles that are the same

      The definition of congruent triangles tells us that when two triangles are con-gruent, each pair of corresponding sides are congruent and each pair of corre-sponding angles are congruent.We use three pairs of corresponding parts, SAS, ASA, or SSS, to prove that two triangles are congruent. We can then conclude

      congruent triangles are congruent, thus cpctc. One way you can determine if two line segments or two angles are congruent is by showing they are the corresponding parts of two congruent triangles. 1. Identify two triangles in which segments or angles are the corresponding parts. 2. Prove the triangles are congruent. 3.

      Proving Triangles Congruent NOTES From yesterday, you learned that you only need 3 pieces of information (combination of angles and sides) to determine if two triangles are congruent. Today, we are going to prove two triangles are congruent using two column proofs. Steps for triangle congruence proofs: 1. Write the ‘givens.’ 2.

      46 Congruence of Triangles Two triangles are congruent if one can be moved on top of the other, so that edges and vertices coincide. The corresponding sides have the same lengths, and corresponding angles are congruent. That is, two triangles ∆ABC and ∆A 0B C0 are congruent if m(∠A) = m(∠A0),m(∠B) = m(∠B0),m(∠C) =

Since DB= DB1 = DB2, the rectangle is also a square.Therefore, DB= D1B1 = D1B2 as well. Now AB1 = AB = 2 so that D1A = D1B1-AB1 =DB-2.
