To locate the point of intersection of two straight lines, we stretch a thread or string between two stakes, where line of sight cuts the string is over required point of intersection.

To locate the point of intersection of two straight lines, we stretch a thread or string between two stakes, where line of sight cuts the string is over required point of intersection. Correct Answer True

Let it be required to locate the point of intersection P of the two lines AB and CD. Set the instrument at A, sight B and set two stakes a and b a short distance apart on either side of the estimated position of point P. Set the instrument at C and sight D. Stretch a thread or string between ab and locate P, where the line of sight cuts the string.

Steps are given to draw an ellipse by loop of the thread method. Arrange the steps. i. Check whether the length of the thread is enough to touch the end of minor axis. ii. Draw two axes AB and CD intersecting at O. Locate the foci F1 and F2. iii. Move the pencil around the foci, maintaining an even tension in the thread throughout and obtain the ellipse. iv. Insert a pin at each focus-point and tie a piece of thread in the form of a loop around the pins.
Arrange the following stages in a sequence, such that they result in an ogee curve between two parallel lines AB and CD, such that they are the tangents to the arc. m) Join the adjacent ends B and C with a straight line. n) Divide the line BC into four parts using the points P1, P2, P3. o) Draw lines such that they pass through the points P1, P2, P3, and are perpendicular to the line BC. p) Draw the perpendicular lines through the points B and C such that they cut the lines passing through P1, P3 respectively at E and F. q) With the center E draw an arc BP2 and with center F draw an arc P2C, thus arc BP2C is required ogee curve.
