When a segment 'm' is dilated by a scale factor 'k' , then the measure of new dilated segment will be 'km' [i.e. New side length =scale factor is multiplied to the original side-length].
Given : An equilateral triangle is dilated by a scale factor of 3.
[Note an equilateral triangle has all its side-lengths are equal.]
Side-length of the original triangle = 6 units
Then, the measure of a side of the new triangle = Scale factor x Original side-length
= 3 x 6 = 18 units
Hence, the measure of a side of the new triangle = 18 units.
Its dimensions are 4 and 9, or you might say this is a 4 by 9 array. We always mention the rows first and then the columns. The multiplication sentence is
According to the associative property of equality: (a + b) + c = a + (b + c) we can see that the parenthesis do not mean anything when we are only doing addition.
