Final answer:
Triangulation is a process where a researcher uses multiple methods to ensure a reliable understanding of a problem, typically by comparing and contrasting different sources of information.
Step-by-step explanation:
Triangulation is a process by which a researcher uses multiple methods to ensure that they have a good 'fix' on a problem.
Triangulation allows researchers to gather data from different angles and perspectives, increasing the reliability and validity of their findings. It involves comparing and contrasting information collected through various methods, such as interviews, surveys, observations, and secondary data analysis.
For example, in geography, triangulation is used to measure distances to inaccessible objects. By getting the angle to a tree from two different vantage points, the properties of the triangle formed can be calculated to determine the distance to the tree.
