draw a line segment of length 7.5 cm and draw its axis of symmetry
Answers
Answer:
Perpendicular bisector is a line of or axis of symmetry for any line segment.
Steps of construction:
Taking A as a centre with radius more than of of a line segment AB draw an arc which intersects C
Taking A as a centre with radius more than of of a line segment AB draw the arcs above and below the line segment AB
Taking B as a centre with the same radius taken before, draw the arcs that will intersect the previously drawn arcs at C and D respectivel;y.
Join C and D
The line CD is the line of axis for the line segment AB
The following steps to construct AB of length 7.5 cm and to find its axis of symmetry.
(1) Draw a line segment AB of 7.5 cm.
2) Taking A as center, draw a circle by using compasses. The radius of circle should be more than half the length of AB.
(3) With the same radius as before, draw another circle using compasses while taking point B as centre. Let it cut the previous circle at C and D
(4) Join CD. CD is the axis of symmetry
