The correct Answer is:
Let's analyze each statement step by step and determine whether they are true or false. ### Step 1: Analyze the first statement **Statement:** "Origin is the only point which lies on both the axes." **Analysis:** - The origin is the point (0, 0). - The x-axis is the line where y = 0, and the y-axis is the line where x = 0. - The only point that satisfies both conditions (x = 0 and y = 0) is the origin. **Conclusion:** This statement is **True**. ### Step 2: Analyze the second statement **Statement:** "The point (2, -2) and point (-2, 2) lies in the same quadrant." **Analysis:** - The point (2, -2) has a positive x-coordinate and a negative y-coordinate, which places it in the **fourth quadrant**. - The point (-2, 2) has a negative x-coordinate and a positive y-coordinate, which places it in the **second quadrant**. - Since these points are in different quadrants, they do not lie in the same quadrant. **Conclusion:** This statement is **False**. ### Step 3: Analyze the third statement **Statement:** "If a point lies on y-axis at a distance of 2 units from x-axis, then its coordinates are (2, 0)." **Analysis:** - A point on the y-axis has an x-coordinate of 0. - If it is at a distance of 2 units from the x-axis, the y-coordinate can be either +2 or -2. - Therefore, the possible coordinates are (0, 2) or (0, -2), not (2, 0). **Conclusion:** This statement is **False**. ### Step 4: Analyze the fourth statement **Statement:** "Abscissa of a point is positive in I quadrant and also in II quadrant." **Analysis:** - The abscissa is the x-coordinate of a point. - In the **first quadrant**, both x and y coordinates are positive, so the abscissa is positive. - In the **second quadrant**, the x-coordinate (abscissa) is negative while the y-coordinate is positive. **Conclusion:** This statement is **False**. ### Final Summary of Statements: 1. True 2. False 3. False 4. False ### Final Answer: - The first statement is **True**. - The second statement is **False**. - The third statement is **False**. - The fourth statement is **False**.
