I didn't know technology was that good nowadays, as a student myself I recommend you this app, its incredibly easy to use but don't depend on it too much. The scale factor, sometimes called the scalar factor, measures how much larger or smaller the image is. And so you can see that the length of AE is equal to two. When radians are selected as the angle unit, it can take values such as pi/2, pi/4, etc. Really great? Similarly, to create a reduced figure, we multiply the original dimensions with the scale factor of 1/2. Another way to describe a scale factor is that it's a multiplier. Observe the following figure which shows how the scale factor can change the original figure to its larger and smaller versions. Scalene triangle (1) height: h= bsinC =csinB (2) angle: B=sin1 h c , C =sin1 h b (3) side: c= a2+b22abcosC (4) area: S= 1 2ah= 1 2absinC = 1 2a2 sinBsinC sin(B+C) =s(sa)(sb)(sc) s= a+b+c 2 S c a l e n e t r i a n g l e ( 1) h e i g h t: h = b sin C = c sin B ( 2) a n g l e: B = sin 1 h c , C = sin 1 h b ( 3) s i d e: c = a 2 + Center of dilation is not the origin Scale factor is how we ensure the representation of the object differs only in size from the original object. So one way to think Therefore, the original dimensions of a triangle were = 3 units, 5 units, and 6 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. .
