So after rotating the point (3, 4) 90 degrees counterclockwise, we get the new point (-4, 3). Negate the new x coordinate: (4, 3) becomes (-4, 3). Swap the x and y coordinates of the point: (3, 4) becomes (4, 3).Ģ. This section covers common examples of problems involving geometric rotations and their step-by-step solutions. ![]() To rotate a point counterclockwise, we can use the following steps:ġ. For a given point (a, b), a 90-degree counterclockwise rotation will result in a new point (-b, a). Step 3 : Based on the rule given in step 1, we have to find the vertices of the reflected triangle ABC. In the field of mathematics, specifically geometry, rotating a point 90 degrees counterclockwise involves changing the coordinates in a certain way. If this triangle is rotated 90 counterclockwise, find the vertices of the rotated figure and graph. Example 1 : Let F (-4, -2), G (-2, -2) and H (-3, 1) be the three vertices of a triangle. So the rule that we have to apply here is (x, y) -> (y, -x). When we rotate a figure of 90 degrees counterclockwise, each point of the given figure has to be changed from (x, y) to (-y, x) and graph the rotated figure. Step 2 : Here triangle is rotated about 90° clock wise. We will rotate this point 90 degrees counterclockwise. Step 1 : First we have to know the correct rule that we have to apply in this problem. To visualize this, imagine a coordinate grid with the positive x-axis pointing to the right and the positive y-axis pointing upward.įor example, let’s consider the point (3, 4) on the coordinate grid. counterclockwise 90 rotation, ( x, y ) is transformed to ( -y, x ). When we rotate an object 90 degrees counterclockwise, we are essentially turning it 90 degrees in the opposite direction of the clock’s movement. 90 Rotation : In the case of a 90 clockwise rotation, the rotation. Rotation 90 degrees counterclockwise When we rotate an object 90 degrees counterclockwise, we are essentially turning it 90 degrees in the opposite direction of the clock’s movement
