∙ 12y agoIf you know how to rotate a triangle around the origin, treat the point as the origin.
If you have Cartesian coordinates (that is x, y pairs) for the points of the triangle,
subtract the coordinates of the centre of rotation from the coordinates of the triangle, do the rotation and then add them back on.
Doing it geometrically:
[The construction lines drawn to the centre of rotation can be erased once the rotated point is found.]

The point where the lines which connect one vertex of the triangle and the middle of the opposite side intersect.
The circumcenter, the incenter is the point of concurrency of the angle bisectors of a triangle.
The three ANGLE bisectors of a triangle also bisect the sides, and intersect at a point INSIDE the triangle. The angle bisectors are not necessarily perpendicular to them. The perpendicular bisectors of the sides can intersect in a point either inside or outside the triangle, depending on the shape of the triangle.
incenter of a triangle
turn it from the middle
To turn around a centre point is to rotate.
it will turn on a pivot point of the triangle.
Trace the triangle on tracing paper, flip the tracing paper so the drawn triangle is touching the paper and then put your pencil on the point (with the tracing paper underneath) that you need to rotate from. Then rotate the paper 90 degrees and draw over the triangle you drew on the tracing paper to stamp it down.
The best way is this:Draw a line from the point closest to the origin to the actual origin. Rotate the line however many degrees you are told, whichever way you are told. After you have the point closest to the origin rotated, you can either rotate the other points the same way or just draw them in based on where the other point lies.Another way, sort of the cheater way, is to just take a piece of tracing paper and trace the figure onto it. Hold it down by pressing your pencil on the tracing paper where the origin is, and rotating it however many degrees, whichever way you are told.This is for ROTATE. To reflect just use the opposite signs on the coordinates.
Circumcenter, this is the center-point of a circle circumscribed around the triangle. If the triangle is obtuse, then this point is outside the triangle and if the triangle is a right triangle, then the point is the midpoint of the hypotenuse.
A rotation
I dont really know if this is right but i think to do this problem you have to take a point then rotate the paper counter clockwise around the origin then you have a new point which is called a prime. Then reflect it over the y axis on the graph.
an epicycle is a system where things rotate around a fixed point.
needs to have a fixed point that it can rotate around
Its a theoretical point, if you threw it in the air spinning, it would rotate around this point.
A triangle, with one of the complex numbers represented by a line from the origin to the number, and then move from that point up and over the amount of the next complex number. Then draw a line segment from the origin to the final point.
