Double fertilization is a characteristic feature of flowering plants. In the process of double fertilization out of the two sperm nucleus, one sperm nucleus fuses with the egg nucleus to form an embryo ( process is called syngamy) and another fuses with polar nuclei to form endosperm ( process is clled triple fusion).
Since two kinds of fusion—syngamy and triple fusion—take place, the process is known as double fertilisation.

the fusion of male and female gametes (example. ovum and sperm in case of mammals) is known as syngamy .
In plants after the fusion of one male gamete with the egg(syngamy) the second male gamete fuses with the two polar nuclei( i.e. the secondary nucleus) leading to the formation of a three nucleate stage . here, since three nuclei fuse together this process is known as triple fusion.
in angiosperms i.e. flowering plants, syngamy and triple fusion both processes take place and thus is known as Double Fertilization .
