Q5. The coordinates of A and B on a number line are -7 and 9. The coordinates
of C and D on a number line -4 and 12. Are AB and CD congruent? If yes, what
is the length of each segment?

Respuesta :

Answer:

  • are congruent
  • length: 16 units

Step-by-step explanation:

The length of a segment on a number line is the difference of its coordinates.

  AB = 9 -(-7) = 16

  CD = 12 -(-4) = 16

AB and CD both have a length of 16 units, so are congruent.
