\triangle PQR is the required triangle which is similar to \triangle ABC.

Step-by-step explanation:

Given,

\triangle PQR is constructed similar to \triangle ABC with scale factor.

Scale Factor:

In two similar geometric figures, the ratio of their corresponding sides is called the scale factor.

Take a \triangle ABC which is Equilateral triangle where all sides and all angles are equal as shown in the figure.

Now,

For \triangle PQR,

PQ=2AB,QR=2BC\ and\ QR=2CA

Also, \angle A=\angle P=\angle B=\angle Q=\angle C=\angle R=60\ degree

Following steps:

  • Draw a line segments QR=2BC using scale.
  • At Q, draw an angle 60\ degree using protector like \angle RQX=60\ degree
  • Also at R, draw an angle 60\ degree using protector like \angle QRY=60\ degree
  • Where line QX\ and\ RY intersect at P

Hence, \triangle PQR is the required triangle which is similar to \triangle ABC.
