This video explains how to determine the scale factor of a dilation by comparing the side lengths of the preimage and image. It demonstrates two methods: dividing the corresponding vertices and finding the ratio of the corresponding...

This video explains how to determine if two figures are similar using dilations and scale factors. It reviews the concept of similar figures, which have the same shape but different sizes and corresponding congruent angles. The video...

This video students will learn how to calculate the actual distance on a map by using a scale. It explains the concepts of ratios, proportions, and scale factors, and provides examples of how to apply them. The video emphasizes the...

This video teaches students how to solve problems involving finding a percent of a number using a proportion model. It explains the concept of a proportion and how to find the scale factor. The video also provides an example problem...

Scale Factors | Ratio & Proportions When you change the size of a shape by making it larger or smaller, the degree to which you change its size is measured by something called its scale factor. A linear scale factor is simply the size of...

This video teaches students how to compute the actual perimeter of a scale drawing by using ratios and proportions. It explains the concept of proportions and demonstrates how to find missing side lengths in similar figures. The video...

In this video, the teacher explains how to change the size of a blueprint by using ratios and proportions. They demonstrate how to solve proportions and use scale drawings to determine actual measurements.

In this video, the teacher explains how to calculate the amount of material needed to make small flags for each student in a school. They demonstrate the use of ratios and proportions to find the area of the flags and apply the concept...

In this video you will see two student character transformation projects. They began by dilating an image in a Google document. They used the draw feature to engineer half inch square graph paper on an 8.5 by 11 in document. Students...

In this video, the teacher explains how to use a photographic enlarger to create a print from a negative while maintaining proper proportions. The lesson also covers solving word problems involving dilations using different scale factors.

In this video, we are going to be looking at Inverse proportion. You may have already looked at direct proportion, which is how we describe the relationship between two quantities which grow by the same scale factor.

Pupil outcome: I can interpret scaled drawings in a variety of contexts. Key learning points: - Maps are a practical example of a multiplicative relationships. - The scale factor is the multiplier. - The multiplicative relationship can...

Pupil outcome: I can recognise the right-angled triangle within a unit circle and use proportion to scale to similar triangles. Key learning points: - There are specific ratios within the two key right-angled triangles defined by the...
