Question

Which piece of information below will not help you prove that triangles ABC and DEF are congruent using ASA?

Answer 1

A)
`AC=DF`

Explanation:

Given

See attachment for triangles ABC and DEF

Options

A)
`AC=DF`

B)
`AB=DE`

C)
`\angle B=\angle E`

D)
`\angle A=\angle D`

Required

Which does not prove the congruence of ABC and DEF using ASA?

From the attachment, we have the following:

`\angle A = \angle D` --- Angle

`AB = DE` --- Side

`\angle B = \angle E` ---- Angle

The ASA theorem means that 1 side of both triangles are equal.

By comparing the listed parameter to the options, we can see that options B, C and D prove that both triangles are congruent by ASA.

However, option A
`AC=DF` cannot be used because that will mean that two sides of both triangles are equal. This does not support the ASA theorem
