Final answer:
Dip and strike are the two measurements used to establish the orientation of deformed strata. Dip refers to the angle at which rock layers incline, and strike is the horizontal line formed when a dipping bed intersects with the surface.
Step-by-step explanation:
The two measurements used to establish the orientation of deformed strata are dip and strike. Dip is the angle at which the rock layers incline from the horizontal, while strike is the horizontal line formed when a dipping bed intersects with the surface.
The dip direction is determined by pouring water on the rock surface to see how it runs, and the strike direction is always 90° counterclockwise from the dip direction.
