Question

15 POINTS !!

The first triangle is dilated to form the second triangle. Select True or False for each statement. Statement True False The scale factor is 0.25. The scale factor is 4. A right triangle with a hypotenuse of 4.4. An arrow points to a smaller right triangle with a hypotenuse of 1.1

Answer 1

Answer: 0.25 is true, so 4 is false.

Scale factor = new size/ original size

scale factor = 1.1 ÷ 4.4

scale factor = 0.25

Answer 2

The scale factor is 0.25, not 4 in this case. You can determine this by looking at the comparison of the triangles. The first triangle is 4.4 and the second one is 1.1, so the scale factor is determined by looking at what is happening to the first one to result in the second.

0.25 is 1/4. The second hypotenuse is 1/4 the hypotenuse of the first one.
