How do people think about us

This app is far by the best math app ive ever had, this app is amazing I was doing homework and it was having a hard time solving it so I looked for an app to download to help me and I came across This app and I'm like this looks pretty good and so I download it I use that I took a picture and it got there a dancer and not only does it tell you the answer but it shows you the steps of how they got the answer it's amazing no, she's just going to think that I actually did it by myself because they're steps there amazing amazing perfect.

SAT Math : How to find out if lines are parallel

Lines can either be parallel or intersecting. When two lines meet at a point in a plane, they are known as intersecting lines. If a line intersects two or more lines at distinct points then it is known as a transversal line. In figure 2, line l intersects lines a and b at points P and Q respectively. The line l is the transversal here. ∠1,∠2,∠ See more
