In the given figure, \(D\) is the midpoint of \(OE\) and \(\angle CDE = 90^{\circ}\). Prove that \(\triangle ODC \equiv \triangle EDC\).

Proof:

	Statement	Reason
1	\(OD = ED\)
2	\(DC = DC\)
3	\(\angle CDE = \angle CDO = 90^{\circ}\)
4	\(\triangle ODC \equiv \triangle EDC\)

Answer variants:

Given that \(D\) is the midpoint of \(OE\).

Common leg

Given that \(\angle CDE = 90^{\circ}\) and \(ODE\) is linear pair.
