Question

distance between the point (1,2)and (-1,-2) is​

Answer 1

Let the given points A(1,2) & B(-1,-2)

By using Distance Formula:-

√(x2 - x1)² + (y2 - y1)²

Here, x1 = 1 & x2 = -1

y1 = 2 & y2 = -2

Putting Values:-

√( -1 - 1)² + (-2 -2)²

√ 2² + 4²

√ 4 + 16

√ 20

Distance between the points (1,2) & (-1,-2) is √20
