**Scaling angles and polygons Illustrative Mathematics**

a triangle using the area of a similar triangle and the scale factor. Explain how you can use a metre stick and shadows to measure the height of an inaccessible object, such as a flagpole or a tree.... If the scale factor is one, then the two shapes are the same, or congruent. The scale factor of the car below to the other car is one. That's not very interesting, so we don't usually talk about

Scale Factor Notes: Explore Video The notes portion of the lesson gives students an opportunity to get a grasp on what scale factor is, and why it is acceptable to drop the units when using scale factor.... To find the scale factor of two triangles, look first for one pair of corresponding sides--one side from the smaller triangle and the corresponding side from the larger triangle. Divide the larger side length by the smaller side length, and that quotient is your scale factor.

**Two similar triangles have a scale factor of 35 What is**

27/11/2018 · The scale factor, or linear scale factor, is the ratio of two corresponding side lengths of similar figures. Similar figures have the same shape but are different sizes. The scale factor is used to solve geometric problems. You can use the scale factor to find the missing side lengths of a figure. Conversely, you can use the side lengths of two similar figures to calculate the scale factor... A scale factor of 1:3 means that one triangle is 3 times bigger than the other, for example. So, if the small triangle has a perimeter of 27, the big triangle has a perimeter 3 times as big. Doing the math, 3*27 = 81 - the big triangle's perimeter, then, is 81 units.

**Seventh grade Lesson Scale Factor BetterLesson**

Let a represent the scale factor of the two squares. Then itfollows that the ratio of the areas is a^2. If these are equal, youget the equation a = a^2, and this is only true Then itfollows that... The triangles are similar because two angles match, and so will the third too. Comparing corresponding sides, we get that the scale factor is 5.85 ? 4.5 = 1.3 y = 1.3 ? 5 = 6.5

## How To Get The Scale Factor Of Two Triangles

### If they were the same scale, they would be the exact same triangles. But one is just a bigger, a blown-up version of the other one. Or this is a miniaturized version of that one over there. If you just multiply all the sides by 3, you get to this triangle. And so we can't call them congruent, but this does seem to be a bit of a special relationship. So we call this special relationship

- Answers:3 meters = 300 cm, so each 2 cm represents 300 cm, i.e. the scale factor is: 2:300 which is the same as 1:150 by dividing both parts by 2. Question: E.G transformation T is a combination of an enlargement and a rotation find the degree of enlargement and angle of rotation.

- Unit 19 Section 3 : Line, area and volume scale factors. In this section we look at what happens to the area of shapes and the volume of solids when the lengths in those shapes or solids are enlarged by a particular scale factor.
- 11/04/2012 · 4/9 because of the fact if u had 2 outstanding triangles. First- an component- 2 b area- 2 component of first is two 2nd- an component is 3 b area is -3 section is 4.5 2/4.5 isn't a perfect ratio, so double the two numbers to get 4/9.
