Solution
Given: AC=7.5cm and ∠A=100∘. Steps for construction Step 1 : Draw a rough figure and mark the given measurements. Step 2 : Draw a line segment AC=7.5cm. Step 3 : At A draw →AX and →AY on either side of ¯¯¯¯¯¯¯¯AC making an angle 50∘ with ¯¯¯¯¯¯¯¯AC. Step 4 : At C draw →CM and →CN on either side of ¯¯¯¯¯¯¯¯CA making an angle 50∘ with ¯¯¯¯¯¯¯¯CA. Step 5 : Let →AX and →CM cut at D and →AY and →CN cut at B. ABCD is the required rhombus. Step 6 : Measure the length BD.BD=d2=9cm.AC=d1=7.5cm.
