Secant & Tangent Pile Walls in Deep Excavations
In a tangent pile wall, there is no pile overlap as the piles are constructed flush to each other. The main advantages of secant pile walls are: 1. Increased construction alignment flexibility. 2. Increased secant pile wall stiffness compared to sheet piles. 3. Can be installed in difficult ground (cobbles/boulders).

$$TX^2 = OX^2-OT^2 =OM^2-OT^2 = (OQ+QM)(OP-QM)-OT^2$$ but since $OP\cdot OQ = OT^2$, $$ TX^2 = QM(OP-OQ)-QM^2 = 2 QM^2-QM^2 = QM^2 $$ as wanted.

Secant plane
Secant planes are similar to tangent planes, which contact the sphere's surface at a point, while secant planes contact the surface along curves. The two-dimensional representations of secant planes are secant lines, the lines that join two distinct points on a curve. wikipedia.org
