The congruency of /_\ mno and /_\ xyz can be proven using a reflection across the line bisecting oz. however, this congruency can also be proven using geometric postulates, theorems, and definitions. prove that the triangles are congruent using a two-column proof and triangle congruence theorems.

given: < m = < x
< n = < y
yo = nz
prove : /_\ mno = /_\ xyz

Δ MNO ≅ ΔXYZ by AAS postulate.

Step-by-step explanation:

Given:

, , and YO = NZ.

Consider YO = NZ

Add OZ on both sides

YO + OZ = NZ + OZ

YZ = NO

Consider triangles Δ MNO and ΔXYZ.

   Statement                                                 Reason

1.                                            Given

2.                                           Given

3. YZ = NO                                            ∵ YO = NZ

Therefore, the two triangles Δ MNO and ΔXYZ are congruent to each other from AAS postulate as two corresponding angles and a corresponding side are equal to each other.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people
