Here is the diagram of the rhombus with all angles labeled and the diagonals shown. Let me know if you'd like further clarification or any adjustments!

Additional Questions to Expand:

1. How can we verify that diagonals of a rhombus always bisect each other at 90 degrees?
2. What happens to the angles if the rhombus becomes a square?
3. How do you calculate the area of a rhombus using its diagonals?
4. Why is it important that opposite angles of a rhombus are equal?
5. How do these angle properties change in other quadrilaterals like parallelograms or rectangles?

Tip:

Always check if the diagonals of a rhombus form right angles to verify it as a rhombus geometrically!
