![]() ![]() The vertices of the quadrilateral are first rotated at 90 degrees clockwise and then they are rotated at 90 degrees anti-clockwise, so they will retain their original coordinates and the final form will same as given A= $(-1,9)$, B $= (-3,7)$ and C = $(-4,7)$ and D = $(-6,8)$. If a point is given in a coordinate system, then it can be rotated along the origin of the arc between the point and origin, making an angle of $90^$ rotation will be a) $(1,-6)$ b) $(-6, 7)$ c) $(3,2)$ d) $(-8,-3)$. And 90 degree rotations are a little bit easier to think about. The image of the point (-4,3) under a rotation of 90º (counterclockwise) centered at the origin is. You see that that is equivalent, that is equivalent to a 90 degrees, to a 90 degrees clockwise rotation, or a negative 90 degree rotation. Rotations are counterclockwise unless otherwise stated. Let us first study what is 90-degree rotation rule in terms of geometrical terms. We're going in a counter-clockwise direction. ![]() If we are required to rotate at a negative angle, then the rotation will be in a clockwise direction. A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction. In both transformations the size and shape of the figure stays exactly the same. rotates points in the xy plane counterclockwise through an angle about the origin of a two-dimensional Cartesian coordinate system. ![]() A figure can be turned clockwise or counterclockwise on the coordinate plane. By applying the counterclockwise rotation matrix to this scenario, the angle of 90 degrees is first converted to radians (/2 radians). Later, we will discuss the rotation of 90, 180 and 270 degrees, but all those rotations were positive angles and their direction was anti-clockwise. A rotation is a type of transformation which is a turn. For instance, consider the task of rotating a character model located at coordinates (5, 3) by 90 degrees counterclockwise for a particular scene. The -90 degree rotation is a rule that states that if a point or figure is rotated at 90 degrees in a clockwise direction, then we call it “-90” degrees rotation. A rigid transformation (also known as an isometry or congruence transformation) is a transformation that does not change the size or shape of a figure.The new figure created by a transformation is called the image.
