Construct a triangle of sides 6cm 8cm and 10cm then construct another triangle whose sides are 3/4 times the corresponding sides of given triangle
Draw AB = 6 cm.
From A, draw arc of 10 cm; from B, arc of 8 cm.
Mark intersection as C.
Join AC and BC.
Draw AB = 6 cm again.
Draw a ray AX. Mark 4 equal parts on it.
Join 4th point to B.
From 3rd point, draw line parallel to it → meets AB at B'.
From A and B', draw arcs of 7.5 cm and 6 cm.
Intersection is C'. Join AC' and B'C'.
