The figure displays two separate triangles, labeled PKX and FST.
Triangle PKX appears to be a right-angled triangle, with the right angle at vertex P. Side PK has markings indicating it is equal in length to side KX. Angle K is not specified.
Triangle FST is also a right-angled triangle, with the right angle at vertex S. Side FS has markings indicating it is equal in length to side ST, making it an isosceles right-angled triangle. Angle F and Angle T are therefore 45 degrees each.
There is no explicit relationship stated or visually implied between the two triangles (e.g., congruence, similarity, or shared vertices/sides).
