![]() ![]() When plot these points on the graph paper, we will get the figure of the image (rotated figure). In the above problem, vertices of the image areħ. Swap the x and y coordinates of the point: (3, 4) becomes (4, 3). ![]() ![]() When we apply the formula, we will get the following vertices of the image (rotated figure).Ħ. To rotate a point counterclockwise, we can use the following steps: 1. BTW: To rotate clockwise, replace (x, y) with (y, -x). What you proposed will flip everything around a 45-degree line that runs from southeast to northwest. When we rotate the given figure about 90° clock wise, we have to apply the formulaĥ. That will rotate 90 degrees counterclockwise about the origin. 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. 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. 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. If this triangle is rotated 90° counterclockwise, find the vertices of the rotated figure and graph. Problem 1 : Let F (-4, -2), G (-2, -2) and H (-3, 1) be the three vertices of a triangle. Here the rule we have applied is (x, y) -> (y, -x). When we rotate a figure of 90 degrees about the origin, each point of the given figure has to be changed from (x, y) to (-y, x) and graph the rotated figure. Most often that point or rotation will be the original but it is important to under. 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). Learn how to rotate a figure and different points about a fixed point. ![]()
