Three bells ring at the interval of 20 minutes, 30 minutes and 40 minutes. when will they ring together if they ring together at 9: 45 am? plz answer the question

Dilation preserve betweenness of points, therefore the corresponding sides of pentagon G and G' are proportional

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional ( this ratio is called the scale factor )and its corresponding angles are congruent

so

The statement that explain why the pentagons are similar is

Dilation preserve betweenness of points, therefore the corresponding sides of pentagon G and G' are proportional
