WebWe will match the corresponding angles and corresponding sides of the two similar polygons below. The following corresponding angles are congruent: ∠Q ≅ ∠L, ∠U ≅ ∠I, ∠A ≅ ∠T, ∠D ≅ ∠E Corresponding sides of similar polygons have a proportional relationship, which can be written as follows: LE DQ = LI QU = TI AU = ET AD WebAgain, s t and m is a transversal, x°, and 70° are corresponding angles hence, they are equal, i.e., x° = 70°. Now, let us assume that the angle that is adjacent to x° is w°. Since x° and w° form a linear pair, x° + w° = 180° 70° + w° =180° w° = 110° Now, w° and z° are corresponding angles, hence, they are equal, i.e., z ... dynabeads myone c1
