The exposure triangle is the term used for the three fundamental elements of exposure: aperture, shutter speed and ISO (international standards organization). The exposure triangle is also a fundamental to learning on how to take good photographs and with these three elements strong images are produced.
Aperture:
A large aperture lets in more light to the camera for an exposure but a small aperture has a smaller opening in the lens to let in less light for a given exposure. As well as this an aperture on a camera is measured in f-stops and it's a size of an iris which controls where the light hits the sensor and how it's focal length. The aperture can also be used for a blurry background and the object at the front would be in focus.
Shutter speed:
A shutter speed is a measurement of the time the shutter speed is open which is shown in seconds or fractions of a second. The shutter speed is also about the speed of the shot and it is low speed in low light and when using a tripod to pick out detail it is high speed to freeze fast moving objects.
ISO:
A ISO is the level of sensitivity of your camera to available light. The lower the ISO number the less sensitive it is to the light while a higher ISO number increases the sensitivity of your camera. ISO is measured in numbers hundred to three thousand and varies depending on the light, speed of shot and density of pixels.

Examples of changes in the camera
In these pictures the light is very overexposed so you can't see the person and sky that much and the ground because the shutter speed is very high and we are letting in too much light so you need to decrease it
In these pictures the light is very underexposed but you can see the people and it's dark and gloomy because of the lack of light that come in the shutter speed so you have to increase it
In these pictures the light and brightness of the picture is perfect and the aperture is almost high so the background is also focused a bit and the quality is coming out good and you can see the people perfectly because I changed the settings of the ISO, aperture and shutter speed
