WebMar 18, 2024 · The condition for two lines to intersect at right angles is that the product of their gradients (slopes) is − 1. Put both equations in the standard form y = m x + c where m is the gradient. Gradient is − 1 2. Hence other line must have gradient of − 1 − 1 2 = 2. Gradient is − k 2. So − k 2 = 2 k = − 4.

WebNov 20, 2024 · 39 - A pipe is to be carried around the right- angled corner of two intersecting corridors. Suppose that the widths of the two intersecting corridors are 5 feet and 8 feet ( see Figure 6- 26). Your objective is to find the length of the longest pipe, rounded to the nearest foot, that can be carried level around the right- angled corner. WebPROPOSITION 14. THEOREM. If two straight lines are on opposite sides of a given straight line, and, meeting at one point of that line they make the adjacent angles equal to two right angles, then the two straight lines are in a straight line with one another. Let two straight lines CB, BD be on opposite sides of the straight line AF, meeting at ...
