Q1 of 12 Page 74

In the given figure, name:

i. any six points


ii. any five line segments


iii. any four rays


iv. any four lines


v. any four collinear points


i) A point specifies the exact location and looks like a small dot.


∴ The points in the given figure are A,B,C,D,E,F,G,H,M,N,P,Q,X,Y.


ii) A part of a line with two end points is a line segment.


∴ The line segment in the given figure are AX,XM,MP,AM,AP,AB,XB,XY…etc


iii) A ray has a starting point but no end point. it may go to infinity.


∴ The ray in the given figure are A,B,C,D,E,F,G,H.


iv) A line goes without end in both direction.


∴ The line segment in the given figure are AB,CD,EF,GH.


v) if three or more points lie on the same line, they are called collinear points


∴ The collinear points in the given figure are AXM,EMN,GPQ,CYN…
