You can then equate these ratios and solve for the unknown side, RT. If you want to know how this relates to the disjointed explanation above, 30/12 is like the ratio of the two known side lengths, and the other ratio would be RT/8. Now that we know the scale factor we can multiply 8 by it and get the length of RT: If you solve it algebraically (30/12) you get: I like to figure out the equation by saying it in my head then writing it out: In this case you have to find the scale factor from 12 to 30 (what you have to multiply 12 by to get to 30), so that you can multiply 8 by the same number to get to the length of RT. Includes 'counting cube' worksheets, as well as activities on using formulas to calculate the volumes of rectangular prisms, cones, pyramids, and spheres.The first step is always to find the scale factor: the number you multiply the length of one side by to get the length of the corresponding side in the other triangle (assuming of course that the triangles are congruent). Congruence Date Period State if the two triangles are congruent.
