Solution
Steps of construction:
- Draw seg AT of length 4.9 cm.
- Take ∠A as 120° and draw an arc of 6.3 cm on it. Name the point as M.
- Join seg MT to obtain ΔAMT.
- Draw ray AB such that ∠TAB is an acute angle.
- Locate points B1, B2, B3, B4, B5, B6, B7 on ray AB such that, AB1 = B1B2 = B2B3 = B3B4 = B4B5 = B5B6 = B6B7.
- Join point T and B7.
- Through point B5 draw a line parallel to seg TB7 which intersects seg AT at point E.
- Draw a line parallel to MT through E to intersect line AM at point H.
∆AHE is the required triangle similar to ∆AMT.
