find the distance between the following pair of point(-3,0),(-1,-2)
Answers
- The distance between the two points (-3, 0) and (-1, -2) is – unit.
Given Points: (-3, 0) and (-1, -2)
Distance between two points is calculated by using the formula given below:
Here:
Substitute the value in the formula, we get:
★ So, the distance between the two points is 2√2 unit.
1. Section formula.
Let P(x₁, y₁) and Q(x₂, y₂) be two points in the coordinate plane and R(x, y) be the point which divides PQ internally in the ratio m₁ : m₂. Then, the coordinates of R will be:
2. Mid-point formula.
Let P(x₁, y₁) and Q(x₂, y₂) be two points in the coordinate plane and R(x, y) be the mid-point of PQ. Then, the coordinates of R will be:
3. Centroid of a triangle.
Centroid of a triangle is the point where the medians of the triangle meet.
Let A(x₁, y₁), B(x₂, y₂) and C(x₃, y₃) be the vertices of a triangle. Let R(x, y) be the centroid of the triangle. Then, the coordinates of R will be:
Answer:
Using distance formula:-
=2×1.414
=2.828
