HI Crosbie Yes, the VIN / Chassis number are the same. Some are now diplayed on the dash board for authorities to check. If there are different in any way, contact you local DVLA office or VOSA for clarification, just in case.... Hope this helps...
In case of a two dimensional plane, two intersecting lines are said to be perpendicular lines if they intersect at right angles. In the figure, the lines $\overleftrightarrow{AB}$ and $\overleftrightarrow{CD}$ are perpendicular to each other intersecting at the point P. We can write.
A perpendicular is a line that is at exactly 90Â° to a base line. They are essential to accurate setting out, and are constructed using one of the fundamental principals of building work, the 3-4-5 triangle. From Pythagoras' theorem, we can establish that any triangle that has side lengths in the ratio of 3:4:5 must be a right angled triangle.
