The problem asks to find the polar coordinates of a point with given rectangular (or Cartesian) coordinates \((1, 0)\), and to express the angle in degrees.

### Steps to convert Cartesian coordinates \((x, y)\) to polar coordinates \((r, \theta)\):
1. **Find the radius \(r\)**:  
   The radius \(r\) is the distance from the origin to the point, calculated as:
   \[
   r = \sqrt{x^2 + y^2}
   \]
   For the point \((1, 0)\):
   \[
   r = \sqrt{1^2 + 0^2} = \sqrt{1} = 1
   \]

2. **Find the angle \(\theta\)**:  
   The angle \(\theta\) is the counterclockwise angle from the positive \(x\)-axis to the point. For the point \((1, 0)\), which lies on the positive \(x\)-axis, the angle is:
   \[
   \theta = 0^\circ
   \]

### Polar coordinates:
Thus, the polar coordinates of the point \((1, 0)\) are:
\[
(1, 0^\circ)
\]

Here are five questions that expand on this topic:
1. How would you convert Cartesian coordinates to polar form for a point not on the axes?
2. What is the relationship between polar and Cartesian coordinates in terms of trigonometry?
3. How do you convert polar coordinates back to rectangular (Cartesian) coordinates?
4. How would the polar coordinates change for a point in different quadrants?
5. What is the significance of the radius \(r\) being negative in polar coordinates?

**Tip:** When converting between Cartesian and polar coordinates, always make sure to check the quadrant to determine the correct angle \(\theta\).

Find the polar coordinates of the point with rectangular coordinates (1, 0). Express the angle in degrees.

Learn how to convert Cartesian coordinates (1, 0) to polar coordinates using key formulas such as r = sqrt(x^2 + y^2) and theta = arctan(y/x). Understand the steps with a focus on expressing the angle in degrees. Suitable for students in Grades 9-11.
