Question

The distance between the points (m,-n) and (-m,n)​

Answer 1

$\boxed{\bf{\red{\bigstar Answer: }}}$

• We can solve this by using distance formulae
• $\sqrt{ ({x 1 - x2})^{2} + ({y1 - y2})^{2} }$
• Suppose
• A(m, -n) = A(x1, y1)
• B(-m, n) = B(x2, y2)
• $\sqrt{ ({m + m})^{2} + (n + n)^{2} }$
• $= \sqrt{4 {m}^{2} + 4 {n}^{2} }$
• $= 2 \sqrt{ {m}^{2} + {n}^{2} }$
