Direct link to bka123's post how would i get the answe, Posted 2 years ago. To find the scale factor, you first decide which direction you are scaling: ScaleUp(smaller to larger) = larger measurement / smaller measurement, ScaleDown(larger to smaller) = smaller measurement / larger measurement. Amazing! So Rectangle N has an I watched the 2 examples in this video but I am, still not sure how to solve this question. KEY STEPS How to Perform Dilations Step 1. The triangle isn't shrinking. Scale factor = Larger figure dimensions Smaller figure dimensions. And so, let's see, Polygon Q First of all, select the number of inputs (number of points). Q's area is one fourth of Polygon P's area and that makes sense because when you scale the dimensions of the Polygon by one half, The scale factor of the right triangle is 1:5. From the source of khan academy: Identify scale factor. The scale factor is the number by which the length of all the sides of a shape has been multiplied to create a . Q.5. If we have the big right triangle and want to scale it down to make the smaller one, we write this: The scale factor of the right triangle is 1:5. Ads come in at a moderate rate, not too much not too little and they deserve the money anyway, also, if you've already written the answer, it can tell younif you're right. For example, you might have a right triangle with sides measuring 4 cm and 3 cm, and a hypotenuse 5 cm long. Anyways, lets move forward: Scale factor of length = Scaled Length/Real Length, Scale Factor = sqrt{(Scale Area/Real Area)}, Scale Factor = * (Scale Volume/Real Volume). Triangle Scale Factor Calculator The scale factor can be calculated when the new dimensions and the original dimensions are given. Area & Perimeter; Sides & Angles; Equilateral.
