Construct a circle through points X, Y. and Z.
Can someone like throughly explain this? I’ve tried many ways and it won’t count it

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

what grade level is this? need to know so i can look in my old textbooks!

their is no graph showing

step-by-step explanation:

f(x)=4
