Swap the elements of the first column with the last column. When we apply the formula, we will get the following vertices of the image (rotated figure).Ħ. Rotate Matrix 90 Degree Clockwise or Right Rotation First, find the transpose of the given matrix. The 90-degree clockwise rotation is a special type of rotation that turns the point or a graph a quarter to the right. Here is the clearer version: The 'formula' for a rotation depends on the direction of the rotation. I hope this helps Edit: I'm sorry about the confusion with my original message above. When we rotate the given figure about 90° clock wise, we have to apply the formulaĥ. If you want to do a clockwise rotation follow these formulas: 90 (b, -a) 180 (-a, -b) 270 (-b, a) 360 (a, b). When we plot these points on a graph paper, we will get the figure of the pre-image (original figure).Ĥ. In the above problem, the vertices of the pre-image areģ. First we have to plot the vertices of the pre-image.Ģ. So the rule that we have to apply here is (x, y) -> (y, -x).īased on the rule given in step 1, we have to find the vertices of the reflected triangle A'B'C'.Ī'(1, 2), B(4, -2) and C'(2, -4) How to sketch the rotated figure?ġ. Here triangle is rotated about 90 ° clock wise. Plot point C’ Note the location of Point C’, the image of Point C after a 90-degree rotation. If this triangle is rotated about 90 ° clockwise, what will be the new vertices A', B' and C'?įirst we have to know the correct rule that we have to apply in this problem. To perform the 90-degree counterclockwise rotation, imagine rotating the entire quadrant one-quarter turn in a counterclockwise direction. Let A(-2, 1), B (2, 4) and C (4, 2) be the three vertices of a triangle. Let us consider the following example to have better understanding of reflection. Here the rule we have applied is (x, y) -> (y, -x). 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. Once students understand the rules which they have to apply for rotation transformation, they can easily make rotation transformation of a figure.įor example, if we are going to make rotation transformation of the point (5, 3) about 90 ° (clock wise rotation), after transformation, the point would be (3, -5). 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.
