Write the name of the diagonals of the following quadrilateral.

2. In the given quadrilateral, vertex $A$ is opposite to vertex $C$ and vertex $B$ is opposite to the vertex $D.$
Therefore, the line joining vertex $A$ to vertex $C$ and the line joining vertex $B$ to vertex $D$ are diagonals of the quadrilateral.
3. Hence, the line segments $AC$ and $BD$ are the diagonals of the given quadrilateral.
