What is Trigonometry about?

The eight-part drama follows Gemma and Kieran, who welcome new flatmate Ray into their London apartment.

However, all three soon realise that they were meant to be together in an unconventional three-way relationship.

The synopsis reads: “Funny and full of sexual tension, Trigonometry has emotional and psychological truthfulness at its heart.”

Creators by Duncan Macmillan and Effie Woods said: “Trigonometry is about negotiating new relationships with compassion and humour.

“Set in a city that can feel cold and unfriendly, at a time when we’re more divided than ever, this is a show about love.”
