Match each set of conditions with the corresponding relationship between ∆abc and ∆xyz and the criterion (if any) that proves the relationship. ab = xy, bc = yz, and angle b is congruent to angle y. ∆abc and ∆xyz are congruent by the sss criterion. ab = xy, and angles a and b are congruent to angles x and y, respectively. ∆abc and ∆xyz are not necessarily congruent. angles a, b, and c are congruent to angles x, y, and z, respectively. ∆abc and ∆xyz are congruent by the sas criterion. ab = xy, bc = yz, and ca = zx. ∆abc and ∆xyz are congruent by the asa criterion.
