Is there a formula you have to know for this type of question?

Hi Anne. Thanks for using the app. This is Coordinate Geometry, which is geometry problems placed in coordinates (basically, numbered checked paper). So you need to know the basic geometry rules for squares and rectangles, triangles, and circles. You know, the angles, areas, circumference, etc.
This question happens to be easy and there is no need for formula. It is solved by simply knowing that the x coordinate of T is the same as that of R (which is the same as Q, since PQRT is a square). And that the y coordinate of T is half of Q.

Gabriela, the explanation is provided in the solution section, and also in the thread by Joel Brainer. Please take time to familiarize yourself with the app before posting questions.

Because I knew the coordinates for Q and that T was the mid point I just counted. is that okay to do?

keri ranzenberger, that's how I did it.

I guessed it write, but I answered (B) because I put the vertical coordination first, is it always horizontal coordination first?

*Sorry ~~auto correct~~ I guessed right

Geo Farah, it is always (x,y)

According to x,y ..shouldn't the ans b 1,2?

Ok ok I got it

This que is from coordinate geometry I don't understand which formula applied in this

This problem is from coordinate geometry what I don't understand is which formula applied in this solution please explain

The Midpoint Formula was applied.

I dont get how is T mid point of QR
