Karthik makes a Glider using two wooden sticks. The longer side (diagonal \(AC\)) is of length \(60 cm\) and shorter side(diagonal \(BD\) of length \(40cm\). The stick intersects at right angles \(O\). such that \(O\) is the midpoint of \(AC\). The ends of the sticks are joined with a paper covering to form a kite \(ABCD\).
Based on the above scenario, answer the following questions:
(i) If \(O\) is the midpoint of \(AC\), find the lengths \(AO\) and \(OC\).
(ii) Glider is a parallelogram. The given statement is true or false.
(iii) The side length of the Glider
(iv) If Karthik decorates the border of the Glider with colour ribbon, how much ribbon is required?
