What does scale factor \(1.5\) mean?Ans: When you want to make a scaled copy, you have to multiply all the lengths of the original figure by a number called the scale factor.In this case, the scale factor \(1.5\) means, while drawing the new figure, we have to multiply all the dimensions of the original figure by \(1.5\). Triangles. Ascale factorin math is the ratio between corresponding measurements of an object and a representation of that object. Since 12 is smaller than 36, it means the original figure has been reduced in size. After that, enter x and y coordinates of all the points one by one. Therefore, the scale factor used to create the smaller polygon is 1/2. Example: You have a shape of a square that has \(16\) units side, and you want to reduce the size by \(25\% \) or, say, one-quarter \(\frac{1}{4}\).Here, the scale factor that is to be used is \(\frac{1}{4}\).So, the new side of the square will be \(= 16 \times \frac{1}{4} = 4\) units. A negative scale factor makes the dilation rotate 180 and it creates an image on the other side of the centre of the enlargement. However, the ratio of the sides of one triangle is equal to the ratio of sides of another triangle. Identify the scale factor used to make the smaller rectangle. . Q.5. If the scale factor is 2, then every coordinate point of the original triangle is multiplied by the scale factor 2. to be equal to three to go from N to P.
