The man in custody, who is in his 20s and knew the family, can be detained for up to 24 hours.
Gardaí said they are not looking for anyone else in connection with the attack.
The house in Rossfield Avenue where the incident occurred remains sealed off
The family home at Rossfield Avenue where the teenager and her younger twins died violently remains sealed off for a second day as forensic specialists continue to examine the crime scene.
A post-mortem examination has been carried out on the body of Lisa Cash. The examinations of the bodies of her twin brother and sister are due to take place today.
All three were stabbed after a man they knew came into their home and attacked them.
Lisa was minding her younger brothers and sisters at the time.
Their 14-year-old brother managed to jump out a window and raise the alarm.
The child was treated in hospital for sustained injuries as he escaped.
