Which theorem or postuate can be used to prove two triangles are similar? thanks in advance
1 answer:
There are two theorems/postulates that we can use; SAS and ASA. These two work because they have properties that force the triangles to retain their shape; no resizing of any sort could be done to them.
See the attached images below to see an example of these triangles. The left one is ASA and the right on is SAS.

Question 1)
Given
Interest I = $18
Principle P = $200
t = 1.5 years
To determine
Interest rate r = ?
Using the formula
susbtituting I = 18, t = 1.5 and P = 200
or
r = 6% ∵ 0.06 × 100 = 6%
Therefore, we conclude that the interest rate required to accumulate simple interest of $18.00 from a principal of $200 over 1.5 years is 6% per year.
Question 2)
Given
Interest I = $60
Principle P = $750
Interest rate = 4% = 0.04
To determine
Time period t = ?
Using the formula to calculate the time period
years
Therefore, the time required to accumulate simple interest of $ 60.00
from a principal of $ 750 at an interest rate of 4% per year is 2 years.
