What is the purpose of a t-bevel in woodworking and how is it used to ensure accurate angle measurements?

A t-bevel is a tool used in woodworking to measure and transfer angles. Its purpose is to help woodworkers accurately replicate and cut angles on their projects. To ensure accurate angle measurements, the t-bevel is adjusted to match the desired angle, then it is used to transfer that angle to the workpiece for cutting or shaping. This helps ensure precise and consistent angles in woodworking projects.
