Question

Quizplus · Accepted Answer

A tongued and grooved joint is a strong and traditional method of joining treads to risers. It involves a slot (the groove) cut into one piece of wood and a corresponding protrusion (the tongue) on the other piece, which fit together tightly to create a strong bond. This method is often used in staircase construction as it allows for a secure and neat installation.
