There are six important properties of parallelograms to know:
<span>Opposite sides are congruent (AB = DC).Opposite angels are congruent (D = B).Consecutive angles are supplementary (A + D = 180°).If one angle is right, then all angles are right.The diagonals of a parallelogram bisect each other.<span>Each diagonal of a parallelogram separates it into two congruent triangles.</span></span>
Answer:
where is the Venn diagram plz insert Venn diagram then I should solve
Step-by-step explanation:
DC is equal to 180°, so subtract 105 from 180.
180-105=75
180 is the total of the the angles when added together.
67°+75°=142
180-142=38
x=38
I guess 26 first question ...
