I have bought some acrylic sheet for replacing the glass in my greenhouse.
On the sheet it suggests cutting it using a jigsaw, a cutting tool or
scoring it and breaking it along the score (a bit like cutting ceramic
tiles
I suppose).

Acrlyic is nasty stuff
A jig saw will either melt it or break it
unless you waste some practicing.
I've found deep scoring effective.
