The triangle is not totally dead.

After the first day of training camp practice, Kristaps Porzingis said there were some triangle actions Jeff Hornacek’s coaching staff reviewed. Somewhere in Montana, exiled president Phil Jackson is smiling.

Porzingis admitted he has no idea if they’ll use that stuff in the gameplan, but it’s not a dead conversation.

“From the first practice we did now, we actually did have some stuff from the triangle,’’ Porzingis said at their Tarrytown campus. “I saw some elements from the triangle. I think it’s always good to know an offense that’s worked in the past. It’s always good for everybody, even if we’re not playing it.

“Just to know some other teams use elements from that offense to defend that better. Or for yourself, for your basketball IQ. We worked on it a little bit today and probably going forward we’re going to do some things with the triangle. It’s going to be good for everybody to know that.’’

In an attempt to take triangle out of the conversation, Hornacek said Tuesday the bigger emphasis is spreading the floor and being more high-tempo this year. In fact, he seemed defensive about the whole idea.

“You guys asked that all last year,” Hornacek said. “Those are basketball actions. If you’re going to throw the ball in the post and run some split actions, you guys want to call it triangle. That’s basketball. Yeah, some of that [we did] we ran last year. That’s just basketball stuff.”

Jarrett Jack, newly signed point guard, said last week he heard no mention of the triangle during voluntary workouts.

Hornacek emphasized again the program will be more about opening up the offense rather than having a confined, slowdown, triangle attack.

“We’re trying to open it up,’’ Hornacek said. “The strength of our team should allow us to do that. Guys like KP from the outside, Courtney [Lee]. Willy [Hernangomez], Enes [Kanter], KO [Kyle O’Quinn], getting it inside to the post guy so we spread the floor. We’ll get up and down the court and put pressure on the defense. That can only start if we can lock down defensively.”

Indeed, Hornacek can run his own show. He attempted to combine his offense with the triangle last season.

When it didn’t work, Jackson ordered a full-blown triangle attack one week before the All-Star Break.

Porzingis’ views on the triangle appear mixed. After he praised the triangle last March, The Post reported Carmelo Anthony reamed him out for being positive in the newspaper.

Perhaps the Cavaliers’ lukewarm interest in Anthony was because they knew Dwyane Wade was on the way.

Responding to Sunday’s Cleveland Plain Dealer report the Knicks asked for Tristan Thompson, the Cavs big responded: “Guess my value is pretty up there, I would say. For Carmelo Anthony? Not bad.”

LeBron James riffed on ex-Knick Derrick Rose, who signed in Cleveland for the veteran’s minimum.

“The kid has a lot to prove from competing against him for so many years, especially in Miami when he was in Chicago and knowing the competitor he’s been over the years,” James told reporters. “Been a fan of him for a long time, and I never thought in my wildest dreams that I’d be a teammate of his.”
