Constructing parallel lines with scale and compass

drawing an arc center radius 2

drawing an arc spiky end of compass pencil end of compass You have to draw with the compass spread this much apart

with alternate angle draw angle = previous angle make an angle

with corresponding angle draw angle = previous angle make an angle

with parallelogram one vertex of parallelogram two equal sides another vertex remaining two equal opposite sides

dividing a line segment equally in 3 pieces with a triangle 3rd side 3 equal corresponding angles divide 2nd line in 3 parts 3 – 1 = 2 lines parallel to 3rd side

dividing a line segment equally in 3 pieces with a pair of parallel lines 1st line equal alternate angles cut 3 – 1 = 2 parts from each line i.e. 2 x 2 = 4 equal segments 2nd line

dividing a line segment equally To divide the line segment in 3 pieces 2 parts were cut from each parallel line How many parts should be cut from each parallel line to divide a given line segment in 7 pieces?
