To show how AAS follows from the definition of congruence, answer the following question. What rigid transformation maps △A"B"C"→△DEF ? (1 point) Responses reflection reflection rotation rotation translation translation dilation

Answer 1

To determine the rigid transformation that maps triangle \( \triangle A''B''C'' \) to triangle \( \triangle DEF \), we need to analyze the properties of the two triangles in relation to each other.

A rigid transformation is a transformation that preserves distances and angles, meaning the shape and size of the figure remain unchanged. The rigid transformations include:

• Translation: Moving every point the same distance in the same direction.
• Rotation: Turning the figure around a fixed point.
• Reflection: Flipping the figure over a line, which produces a mirror image.

Given the options provided, and without specific information about the positions of the triangles, we can summarize:

• If triangle \( \triangle A''B''C'' \) can be moved to triangle \( \triangle DEF \) without changing its shape or size, you would determine if it's through translation, rotation, or reflection.
• If the two triangles are congruent and can be aligned perfectly through any of these transformations, that indicates congruence.

Since I don’t have specific details about the triangles or their orientations, I'll provide a general response:

• If you are trying to align the triangles without flipping them, a rotation or a translation would be appropriate.
• If the triangles need to be flipped to match, then a reflection is necessary.

If you can provide more specific conditions or orientations of the triangles, I can give a more precise answer. But based on the definitions of rigid transformations, you might select translation, reflection, or rotation depending on the context you have, but not dilation, since that does not preserve congruence.

(1 point) Responses BG¯¯¯¯¯¯¯¯≅CW¯¯¯¯¯¯¯¯¯ Modifying above upper B upper G with bar congruent to Modifying above upper C upper W with bar GB¯¯¯¯¯¯¯¯≅WC¯¯¯¯¯¯¯¯¯ Modifying above upper G upper B with bar congruent to Modifying above upper W upper C with bar BI¯¯¯¯¯¯≅CO¯¯¯¯¯¯¯¯ Modifying above upper B upper I with bar congruent to Modifying above upper C upper O with bar ∠I≅∠O

Answer 3

To prove that triangles \( \Delta BIG \) and \( \Delta COW \) are congruent using the AAS (Angle-Angle-Side) Congruence Theorem, we need two angles and the side that is not between those angles to be congruent.

Given the listed responses, we can analyze what additional information you have that would support the AAS theorem. The AAS theorem requires:

• \( \angle B \) must be congruent to \( \angle C \).
• \( \angle I \) must be congruent to \( \angle O \).
• One pair of non-included sides must also be congruent.

Looking at the responses, the option that explicitly states an angle congruence would be ideal in confirming the AAS condition.

For example:

• \( \angle I \cong \angle O \)

This option indicates that you already have two angles of triangle \( \Delta BIG \) and triangle \( \Delta COW \) (the third angle can be inferred since the sum of the angles in a triangle is \( 180^\circ \)).

Additionally, if you have the congruence of any of the non-included sides, like:

• \( BG \cong CW \) or \( GB \cong WC \)

These would also be supportive of the congruence claim when combined with the angles.

However, in the context of the AAS theorem's direct application, the option that indicates:

• \( \angle I \cong \angle O \)

is specifically addressing the angle condition necessary for the theorem.

Thus, the best response that proves \( \Delta BIG \cong \Delta COW \) using AAS would be:

• \( \angle I \cong \angle O \).

Answer 4

If ΔLAF≅ΔNOW, find the length of LF¯¯¯¯¯¯¯. (1 point) Responses 7 7 12 12 5 5 3

Answer 5

To determine the length of \( \overline{LF} \) given that \( \Delta LAF \cong \Delta NOW \), we can use the properties of congruent triangles. When two triangles are congruent, corresponding sides are equal in length.

The triangle pairs can be matched as follows based on standard notation:

• \( L \) corresponds to \( N \)
• \( A \) corresponds to \( O \)
• \( F \) corresponds to \( W \)

This means that if \( \Delta LAF \cong \Delta NOW \), then:

• \( LA \equiv NO \)
• \( AF \equiv OW \)
• \( LF \equiv NW \)

To find the length of \( \overline{LF} \), you would look for the length of the corresponding side \( NW \) in triangle \( \Delta NOW \). However, since the specific lengths of sides in either triangle are not provided in the question, we can't deduce \( \overline{LF} \) without that information.

To solve this question, you need to know the lengths of the corresponding sides or a specific length from either triangle. If you found such lengths in your material that correlate to the answer choices (7, 12, 5, 3), you would select one based on the corresponding triangle information.

If you have additional context or values associated with either triangle \( \Delta LAF \) or \( \Delta NOW \), please provide that, and I could assist you further in determining \( \overline{LF} \).
