Sample questions
- Q: How do you check whether three points are collinear using distances?
- A: They are collinear if the largest distance equals the sum of the other two distances (the three points lie on one straight line).
- Q: What are the coordinates of a point?
- A: An ordered pair (x, y) giving the point's horizontal distance x and vertical distance y from the origin.
- Q: What is the origin?
- A: The point (0, 0) where the x-axis and y-axis cross.
- Q: What is the distance formula between two points?
- A: d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}.
- Q: Find the distance between (0,0) and (3,4).
- A: d = \sqrt{3^2 + 4^2} = \sqrt{9 + 16} = \sqrt{25} = 5.
