The diagram represents a reduction of a triangle by using a scale factor of 0.8.

4.8 inches

Step-by-step explanation:

See comment for complete question

Represent the larger triangle with 1 and the smaller with 2.

So, we have:

-- height of 1

Required

Determine H2 --- Height of 2

To do this we apply dilation formula.

In this case:

Substitute 6 for H1 and 0.8 for Scale Factor

Hence, the height of the smaller triangle is 4.8 inches

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
