Given A(-5,1), B(-1,3), C( 1,4), and D(4,1), is line segment AB about the same length as line segment CD? Explain.
+129840 Given A(-5,1), B(-1,3), C( 1,4), and D(4,1), is line segment AB about the same length as line segment CD? Explain.
Using the distance "formula" AB = √[( -5 - (-1))2 + (3 - 1)2 ] = √[(-4)2 + (2)2] =
√[16 + 4] = √20
And CD = √[( 4 - 1)2 + (4 - 1)2 ] = √[(3)2 + (3)2] = √(9 + 9) = √18
So AB ≠ CD
