Question

construct triangle ln which BC= 6.5 cm AB=4.5 and,abc =60 construct a similar triangle whose side are3/4 of ABc​

Answer 1

$\bold{1.BC = 6.5 cm \: is \: drawn.}$

$\bold{2. At \: point \: B, \: AB = 4.5 cm \: is \: drawn \: making \: an \: ∠ABC \: =60° \: with \: BC.}$

$\bold{3. AC \: is \: joined \: to \: form \: ∆ ABC.}$

$\bold{4. A \: ray \: BX \: is \: drawn \: making \: an \: acute \: angle \: with \: BC \: opposite \: to \: vertex \: A.}$

$\bold{5. \: 4 \: points \: B_{1} \: B_{2} \: \: B_{3} \: \: B_{4} \: are \: marked \: at \: equal \: distances \: on \: BX}$

$\bold{6.B_{3} \: is \: joined \: with \: C \: and \: B_{4}C` \: is \: \: made \: parallel \: to \: B_{3} C.}$

$\bold{7.C`A \: is \: drawn \: parallel \: to \: CA.}$

$\bold{ \therefore \: A`BC` \: is \: the \: required \: triangle.}$
