Write the name of the diagonals of the following quadrilateral.

Answer:
AC and BD
- A diagonal of a quadrilateral is a line segment joining one vertex of the quadrilateral to the opposite vertex.
- 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. - Hence, the line segments AC and BD are the diagonals of the given quadrilateral.
