- Drag the vertices around to change the size/shape of the triangle. - Click the boxes at the top to show/hide the lines/point of concurrency. - Click the arrows on either side of the words to view different lines/points of concurrency (the first word is the lines and the second word is the point of concurrency). - Press space to show secondary lines - Press "H" to hide coordinates and buttons - The top coordinate on the left is the coordinate of the shown point of concurrency. - The bottom three coordinates on the left are the vertices of the triangle. LINES AND POINTS OF CONCURRENCY: - There are four lines - medians, altitudes, perpendicular bisectors, and angle bisectors - and four points of concurrency, where the corresponding lines intersect - centroid, orthocenter, circumcenter, and incenter. - Medians go from one vertex to the midpoint of the opposite side. They intersect at the centroid. - Altitudes are perpendicular to one side and go through the opposite vertex. They intersect at the orthocenter - Perpendicular bisectors lie on the midpoint of a side and are perpendicular to that same side. They intersect at the circumcenter. - Angle bisectors go through the middle of the angle at a vertex. They intersect at the incenter.
Thank you to @UnscrambledEgg for a handy thumbnail trick. It might bug out sometimes, because Scratch can't handle vertical lines (a.k.a. lines with an undefined slope). Does anyone know how to fix this?
