Coordinate planes: Do any of you know any nemonic devices or anything to help me remember quadrant numbers and the positive and negative signs? I have trouble remembering and anytime I look anything up Edgenuity kicks me out because it insists on being cancer.

Step-by-step explanation:

Hello!!!

I can understand how you feel about this. I hope to do my best in helping you understand quadrant numbering and signs.

Now for the number start form the top right and move counter-clockwise, that is

Top right =1st quadrant

Top left = 2nd quadrant

Bottom left = 3rd quadrant

Bottom right =4th quadrant

Basically moving counter-clockwise you will get this

Now for the sign convection

Up and right are both positive

Down and left are both negative.

I hope this helps. Don't forget to let me know should you need any further assistance.

Regards.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
