If the dimensions of a triangle are cut in half, then the new permeter is one fourth of the original perimeter true or false

False. It is half as large.

Step-by-step explanation:

The best way to answer a question like this is to try an example. The easiest case is an equilateral triangle where all 3 sides are equal. So suppose that all sides are 10 units long.

The perimeter (P) is 3s. Let

You are instructed to cut all sides in half

The perimeter is 1/2 as larger as the original, not 1/4. The statement is FALSE.

Does this work with any triangle. Try one that is Scalene (no side equals any other side).

Now you cut all three sides in 1/2

9 is 1/2 of 18. The new perimeter is 1/2 the old. The statement is false.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
