Q25 of 47 Page 1

Draw an isosceles triangle ABC in which the base BC is 8 cm long and its altitude AD through A is 4 cm long. Then draw another triangle whose sides are of the corresponding sides of ∆ABC.


Steps:


1) Draw BC of 8 cm


2) Find the midpoint of BC at 4 cm from either side and mark it as D


3) Draw a perpendicular from point D of 4 cm and mark this point as A


4) Join AB and AC


5) Draw a line from B of any length


6) Using a compass cut out 3 equal lengths of any dimension on this line


7) Mark the end point as P


8) Join PA


9) From the second node draw a parallel line using two set squares to meet the line AB


10) Mark this point as E


11) Draw another line from point E parallel to AC


12) Mark this point as F


Answer: Triangle ABE is the required triangle
