Question

construct an isosceles triangle whose base is 8 cm and altitude is 4 cm and then construct another triangle whose sides are 3/4 times the corresponding sides of isosceles triangle

Answer 1

Answer:

Construct line a b of 8 cm

draw a perpendicular bisector of a b

by taking D as center draw an Arc of 4 cm and join DC

join AC and BC the triangle is formed

from a draw an acute angle of any measure

take an arc of 1 cm and cut into three parts b1 b2 b3

join B2 and b

extend B to B ' and joint B3 to b' which is // to B2B

similarly join b'c'//bc

join ac' we get the new triangle i.e. ab'c'
