Yes, quadrilaterals can have right angles, but not all of them do. A quadrilateral is any four-sided polygon, and it can have a variety of angle types depending on the specific type of quadrilateral. Some quadrilaterals, such as rectangles and squares, are specifically defined by having right angles.

Here are some types of quadrilaterals and their relationship with right angles:

1. Rectangle: A rectangle always has four right angles (90°). So, yes, it does have right angles.
2. Square: A square is a special type of rectangle where all sides are equal, and it also has four right angles.
3. Rhombus: A rhombus generally does not have right angles, but if all angles are 90°, it becomes a square.
4. Parallelogram: A parallelogram does not generally have right angles, but if all angles are 90°, it is a rectangle.
5. Trapezoid (or Trapezium in some countries): Trapezoids may or may not have right angles, depending on the specific shape.
6. Kite: A kite may or may not have right angles, but it generally doesn’t unless it's a specific type (like a square).

2. What are the properties of a square compared to a rectangle?
3. How do the angles of a rhombus differ from those of a square?

5. Can a quadrilateral have more than four right angles?

Tip: When identifying types of quadrilaterals, check the angle measurements first, then the side lengths!
