Question

Geometry Help Please!

Answer 1

The table below shows the steps to prove that if the quadrilateral ABCD is a parallelogram, then its opposite sides are congruent:

Statement 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 interior 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 2

Which statement is true about the table?

It is not correct because it provides incorrect sequence of statement 3 and statement 4.
It is not correct because it does not show correct reasons for statement 2 and statement 4.
It is accurate because it shows why a parallelogram has four sides.
It is accurate because it provides the correct reasons for the statements.
