1)
\overline{AB} \cong \overline{CD},
\overline{AD} \cong \overline{CB},
\overline{AX} \perp \overline{BD},
\overline{CY} \perp\overline{BD} (given)

2)
\overline{BD} \cong \overline{BD} (reflexive property)

3)
\triangle ABD \cong \triangle ACDB (SSS)

4)
\angle ADB \cong \angle CBY (CPCTC)

5)
\angle CYB and
\angle AXD are right angles (perpendicular lines form right angles)

6)
\triangle CYB and
\triangle AXD are right triangles (a triangle with a right angle is a right triangle)

7)
\triangle AXD \cong \triangle CYB (HA)

8)
\overline{AX} \cong \overline{CY} (CPCTC)
