Answer:

b. DAC≅DBC

Step-by-step explanation:

∠DCB≅∠DCA=90° as they are right angles at the perpendicular lines

DC=DC reflexive property(they are the same line)

AC=CB they are both the radius of the same circle

DAC≅DBC   due to SAS(Side angle Side)

Answer:

Step-by-step explanation:

If we reflect triangle BCD about the line perpendicular to the diameter, it will coincide exactly with triangle DAC; the two triangles are congruent.
