the two lines are parallel.

(ii) The diagonals of a parallelogram bisect each other

Answer 1

Answer:

tell me what is confidential form

Answer 2

i. If a figure is a triangle, then the sum of the measures of its angles is 180°.

ii. if two angles are complement of each other, then sum of their measures is 90°,

iii. If two lines are parallel, then the corresponding angles formed by a transversal of two lines are congruent.

iv. If a number is divisible by 3, then the sum of its digits is also divisible by 3.
