Question

Пропорциональны ли отрезки AB,CD и MN,KL ,если AB=2 CD=6 MN=3 KL=9

Answer 1

$\frac{cd}{ab} = \frac{kl}{mn}$
$\frac{6}{2} = \frac{9}{3}$
$3 = 3$
Ответ : да

Answer 2

Two line segments are said to be proportional if the ratios of their lengths are equal. In this case, we need to compare the ratios of AB to CD and MN to KL to determine if they are proportional.

To check if the segments are proportional, we calculate the ratios:

1. Ratio of AB to CD: AB = 2 CD = 6 Ratio AB/CD = 2/6 = 1/3

2. Ratio of MN to KL: MN = 3 KL = 9 Ratio MN/KL = 3/9 = 1/3

Both ratios are equal to 1/3. Therefore, the two pairs of line segments AB, CD, and MN, KL are proportional.
