How Do You Find Missing Measurements of Similar Figures Using a Proportion?

Trying to find a missing measurement on similar figures? Make ratios from corresponding sides and set up a proportion! Solve the proportion to get your missing measurement. Figure out how to do all that by watching this tutorial!
What are Similar Figures?

Looking at two figures that are the same shape and have the same angle measurements? You have similar figures! Learn all about it in this tutorial!
What is a Scale Drawing?

Without a blueprint, it would be really hard to construct a building. Without a road map, you'd be lost! Scale drawings make it easy to see large things, like buildings and roads, on paper. Even a GPS uses scale drawings! Check out this tutorial to learn all about scale drawings.
How Do You Solve a Problem Using Indirect Measurement with Shadows?

Word problems allow you to see the real world uses of math! This tutorial shows you how to take a word problem and use indirect measurement to turn it into a proportion. Then see how to use the mean extremes property of proportions to cross multiply and solve for the answer. Take a look!
What are Corresponding Parts in Similar Figures?

Identifying corresponding parts in similar figures isn't so bad, but you have to know what you're looking for. This tutorial does a great job of explaining the corresponding parts of similar figures! Take a look!
How Do You Solve a Proportion Using Cross Products?

Want to solve a percent proportion? Just use the means extremes property of proportions to cross multiply! Solve for the variable, and you have your answer! Learn how with this tutorial.
What's a Proportion?

The idea of proportions is that a ratio can be written in many ways and still be equal to the same value. That's why proportions are actually equations with equal ratios. This is a bit of a tricky definition, so make sure to watch the tutorial!
What's the Means-Extremes Property of Proportions?

The means-extremes property of proportions allows you to cross multiply, taking the product of the means and setting them equal to the product of the extremes. This property comes in handy when you're trying to solve a proportion. Watch this tutorial to learn more!
What's a Ratio?

Ratios are everywhere! The scale on a map or blueprint is a ratio. Ingredients sometimes need to be mixed using ratios such as the ratio of water to cement mix when making cement. Watch this tutorial to learn about ratios. Then think of some ratios you've encountered before!
What are the Means and Extremes of Proportions?

A proportion is just an equation where two ratios are equal, and each piece of the proportion has a special name. This tutorial will teach you those names, and this will help you understand cross multiplication when you learn it later!
How Do You Solve a Word Problem Using a Proportion?

This tutorial provides a great real world application of math. You'll see how to use the scale from a blueprint of a house to help find the actual height of the house. This tutorial shows you how to use a proportion to solve!
How Do You Use the Triangle Proportionality Theorem to Find Missing Lengths in a Diagram?

This tutorial shows you how the Triangle Proportionality Theorem can be used to find a missing length in a diagram. Take a look!
How Do You Write a Ratio From a Word Problem?

Sometimes the hardest part of a word problem is figuring out how to turn the words into a math problem. In this tutorial, you'll see how to take the information given in a word problem and write a ratio. Then, reduce the ratio and explain its meaning. See it all in this tutorial!
How Do You Find a Scale Factor in Similar Figures?

Have similar figures? Want to find the scale factor? Then check out this tutorial! You'll see how to use measurements from similar figures to create a ratio and find the scale factor.
How Do You Solve a Scale Model Problem Using a Scale Factor?

This tutorial provides a great real world application of math! You'll see how to use the scale on a house blueprint to find the scale factor. Then, see how to use the scale factor and a measurement from the blueprint to find the measurement on the actual house! Check out this tutorial and see the usefulness blueprints and scale factor!
How Do You Find the Scale of a Model?

Want some practice with scale? Then check out this tutorial and you'll see how to find the scale of a model given the lengths of the model and the actual object. Take a look!
How Do You Use the Scale on a Map to Find an Actual Distance?

Maps help us get from one place to another. In this tutorial, you'll learn how to use a map to find an actual distance.
What is a Dilation?

When someone's eyes dilate, their pupils get bigger or smaller, but they always stay the same shape. Dilation in math is very similar. When you dilate a figure, you change the size of the figure without changing its shape. This tutorial introduces you to dilation. Take a look!
What is a Scale?

In math, the term scale is used to represent the relationship between a measurement on a model and the corresponding measurement on the actual object. Without scales, maps and blueprints would be pretty useless. Check out this tutorial and learn about scale factor!
How Do You Find the Angles in a Triangle if You Have a Ratio of Their Measures?

Looking for the measurements of the interior angles of a triangle? Then check out this tutorial! You'll see how to use a given ratio of the interior angles and the Triangle Sum theorem to find those missing measurements. Take a look!
