Atriangle can be formed with side lengths 3 in, 5 in, and 9 in.
true
false

False

Step-by-step explanation:

To find out if you can form a triangle from the measurements, you can compare the numbers.

If you add any combination of these number together, they need to be greater than the one you're comparing to.

3 + 5 needs to be greater than 9.

But it's not.

The other combinations work:

3 + 9 > 5

9 + 5 > 3

But since the first combination didn't work, these measurements will not form a triangle.

Hope I helped :)

(I know this answer is 3 years late but I just took the test and got it right.)

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
