![]() ![]() Enlarge the triangle by a scale factor of 2. For instance, you can get a reflection on your math ability by analyzing a math problem. ![]() If the scale factor is 1/2, draw lines which are 1/2 as long, etc. A Reflection On My Math Self A reflection is a way of evaluating a problem. If the scale factor is 3, draw lines which are three times as long. Measure the lengths of each of these lines.Ģ) If the scale factor is 2, draw a line from the centre of enlargement, through each vertex, which is twice as long as the length you measured. The resultant position of the shape on the tracing paper is where the shape is rotated to.Įnlargements have a centre of enlargement and a scale factor.ġ) Draw a line from the centre of enlargement to each vertex ('corner') of the shape you wish to enlarge. essay/reflection - mathematics in modern world for midterms and finals midterms reflection paper studying in the midst of pandemic is quite challenge whole. Push the end of your pencil down onto the tracing paper, where the centre of rotation is and turn the tracing paper through the appropriate angle (if you are not told whether the angle of rotation is clockwise or anticlockwise, it would usually be anticlockwise). For more resources, see my Writing in Math Class page. One of the best parts of reflection is how much it gets you thinking about the future. If you wish to use tracing paper to help with rotations: draw the shape you wish to rotate onto the tracing paper and put this over shape. The process which turns a difficult problem into a relatively easy problem is the beauty of math. To describe a reflection, we need to say where the line of reflection. When describing a rotation, the centre and angle of rotation are given. Every point on the shape is reflected in a line of reflection. ![]() The distance of each point of a shape from the line of reflection will be the same as the distance of the reflected point from the line.įor example, below is a triangle that has been reflected in the line y = x (the length of the pink lines should be the same on each side of the line y=x): When describing a reflection, you need to state the line which the shape has been reflected in. A reflection is like placing a mirror on the page. ![]()
