What is the common angle of triangle PQT and triangle RSQ? Can someone explain this for me ?

The common angle of triangle PQT and triangle RSQ is the angle they both share, which is at vertex Q. In the context of the triangles mentioned, if triangle PQT and triangle RSQ are connected at point Q and share a common side, then the angle at Q would be the common angle in both triangles. To understand this, one must recall that a triangle is a three-sided figure lying on a plane, with the sum of its internal angles adding up to 180 degrees, a foundational concept in geometry.
When two triangles have a common vertex and a common side, as seems to be the case with triangles PQT and RSQ, they will have a common angle at that vertex. The angle at vertex Q is, therefore, the common angle between these two triangles. This concept is part of triangle congruence and similarity—when two triangles have one or more congruent angles or sides.

The common angle of triangle PQT and triangle RSQ is the angle at vertex Q, which both triangles share due to their connection at this vertex. This shared angle is essential in understanding the properties and relationships of triangles. Recognizing common angles helps in studying triangle congruence and similarity.
