Answer 2

Statements
Reasons
1
AB is parallel to DC and AD is parallel to BC
definition of parallelogram
2
angle 1=angle 2, angle 3=angle 4
if two parallel lines are cut by a transversal then the alternate angles are congruent
3
BD = BD
Reflexive Property
4
triangles ADB and CBD are congruent
if two angles and the included side of a triangle are congruent to the corresponding angles and side of another triangle , then the triangles are congruent
5
AB = DC , AD = BC
corresponding parts of congruent triangles are congruent

Answer 3

Which statement is true about the table?

It is not correct because it provides incorrect sequence of statement 3 and statement 4.

It is accurate because it provides the correct sequence of statements and reasons.

It is accurate because it provides proof for why a parallelogram has four sides.

It is not correct because it does not provide correct reasons for statement 2 and statement 4.
