For the picture below: XY = 8, CD = 8. <X = 87 degrees, <Z=57 degrees, <D = 36 degrees and <B = 57 degrees. Part 2. Write a correct congruency statement. You may use the = instead of the congruency symbol. (2pts)

To write a congruency statement based on the information you've provided, we need to identify which triangles or figures are congruent. Given the angles and side lengths, we have:

  • \( XY = 8 \)
  • \( CD = 8 \)
  • \( \angle X = 87^\circ \)
  • \( \angle Z = 57^\circ \)
  • \( \angle D = 36^\circ \)
  • \( \angle B = 57^\circ \)

From this information, we can deduce that triangles that can be considered congruent must have equal corresponding sides and angles. Notably, we have:

  • Two pairs of angles that are equal: \( \angle Z \) and \( \angle B \) both equal \( 57^\circ \).
  • If \( \angle D = 36^\circ \) corresponds to another angle in the first triangle, we can also find that the last angle \( \angle Y \) should satisfy the triangle sum theorem.

To clearly write a congruency statement, further details about the triangles themselves are necessary (e.g., which triangle is which). Assuming we denote two triangles as \( \triangle XYZ \) and \( \triangle BCD \):

If we determine that \( \triangle XYZ \) and \( \triangle BCD \) have corresponding angles and sides, we could express their congruency like this:

\[ \triangle XYZ = \triangle BCD \]

This statement indicates that the two triangles are congruent based on the provided measures. If you could provide more context regarding the orientation or relationships between the angles and sides, a more specific congruency statement could be crafted.
