1. Lines joining points (-4, 0), (0, 5) and (4, 0) will form
- A. a circle
- B. a circle
- C. a circle
- D. a circle
Answer: Option D
Explanation:
Let the points be A( - 4, 0), B(0, 5) and C(4, 0).
Now, AB = √{( - 4 - 0)2 + (0 - 5)2} = √41
BC = √{(0 - 4)2 + (5 - 0)2} = √41
CA = √{(4 + 4)2 + (0 - 0)2} = 8
Here, AB = BC. So, the triangle will be an isosceles triangle.
