Answer 1

Respuesta:
Pará saber si son proporcionales

A)
AC/A'C' = BC/B'C'
3/7 = 2/(14/3)
3/7= 6/14
3/7= 3/7.

A) SI SON PROPORCIONALES LOS DOS TRIÁNGULOS.

B) AC/DE= AB/DF
3/7,5= 2/5
(3/1)/(75/10)= 2/5
30/75= 2/5
2/5= 2/5

LOS DOS TRIÁNGULOS SI SON PROPORCIONALES.

C)
A'B'= √C² - a²
A'B'= √15² - 9²
A'B'= √225 - 81
A'B'= √144
A'B'= 12

BC/B'C' =AC/A'C'
13/15 = N/9
N= (13X9)/15
N= 7,8

AB/A'B= BC/B'C'
AB/12= 13/15
AB= (13x12)/15
AB= 156/15
AB= 10,4

AB/A'B=BC/B'C'= =AC/A'C'
10,4/12 = 13/15= 7,8/9
(104/10)/12= 13/15 = (78/10)/9
104/120 = 13/15= 78/90
13/15= 13/15= 13/15

Si es congruente.

D)
AB/A'B'= AC/A'C'
3/6= 3/A'C'
A'C'= (3/1)/(3/6)
A'C= 18/3
A'C'= 6

AB/A'B'= BC/B'C'= AC/A'C'
3/6= 3√2/6√2= 3/6
1/2= 1/2= 1/2

Si es congruente o proporcionales.
