Roland said it is possible to make a triangle from the following lengths: 31 inches, 70 inches, and 37 inches. He explained that 101 inches is greater than 37 inches and the
class agreed. What should now happen?
O The teacher should be happy. They are correct!
The teacher should be sad. The correct answer is 68 inches is NOT greater than 70 inches
therefore a triangle can't be created.

the teacher should be sad. the correct answer is 68 inches is NOT greater than 70 inches, therefore a triangle can't be created

Step-by-step explanation:

in a triangle, 2 sides added together have to be greater than the third side or else the triangle can't be created. therefore, since 31+37=68 inches, and 68<70, the triangle can't be created.

linear pair postulates

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
