Distance from a point to a line the perpendicular "R". Draw the vertical line through "P" and label its intersection with the given line "S". At any point "T" on the line, draw a right triangle "TVU" whose sides are horizontal and vertical line segments with hypotenuse "TU" on the given line and horizontal side of length |"B"| (see diagram). The vertical side of ∆"TVU" will have length |"A"| since the line has slope -"A"/"B". ∆"PRS" and ∆"TVU" are similar triangles, since they are both right triangles and ∠"PSR" ≅ ∠"TUV" since they are corresponding angles of a transversal to the parallel lines "PS" and "UV" (both
Borough of Wokingham closest higher education provider is the main Whiteknights Park campus of the University of Reading immediately north-west. Elevations range between 30 and 70 metres above sea level except higher in about 5% of the borough. The highest is an escarpment containing parts of the rural and wooded northern area, the hinterland of three Thames-side villages, facing the 30-mile long Chilterns AONB, west and north. A geological part of that range of hills, Bowsey Hill reaches 137m, in Wargrave civil parish, from the river. Approximately a right-angled triangle, the borough is long north to south. It uses as its longest edge
