A projector includes a main body and an optical assembly. The main body forms an image and projects the image to a first screen through a lens of the main body. The optical assembly is detachable from the light path of the lens, and is used for reflecting light beams emitted from the lens to project an image on a second screen when the optical assembly is in the light path of the lens. When the optical assembly is detached from the light path of the lens, the optical assembly projects the image on the first screen. The first screen and the second screen are on two adjacent perpendicular surfaces, such as a wall and a ceiling.
