What is the scale factor used to dilate from small to big triangle?

You need numbers from the sides of the triangles. Take numbers from the corresponding (matching) sides, one number from the small triangle, and one number from the big triangle. Then divide the big number by the small number. The answer is the scale factor.
Put another way, the scale factor is the number that multiplies the small triangle to create the large triangle.

What is true about the area of similar triangles when the sides are increased by the factor of two?
when you multiply the area of the small triangle by four it equals the area of the large triangle.
Does one inch equal the same of real miles on all maps why or why not?
No one inch on am map is not a mile reason is because not all maps are made in scale EX: say you have a huge map and a small map one inch on the big map might be a mile but you should check the scale on the small map if used the same scale could tell you it's one mile form Chicago to New York City
Why is it impossible for a triangle to a contain a 180 angle?
The sum of all three angles in a triangle is 180 degrees. If one angle has 180 degrees then there are no degrees left for the other two. If it is a fraction less than 180 degrees then the other could split up the small fraction.
What is the interior angle of a twenty sided polygon?
A twenty-sided polygon is called an "icosagon" If it is a regular icosagon - all its sides and angles are equal - then it's interior angles are all 162 degrees. You can verify this by drawing a line to the centre from each angle.. There will be 20 small angles arranged in a circle around the centre. These must total 360 degrees. As 360 / 20 = 18, this leaves the other angles of each triangle to add up to 162, because the interior angles of a triangle total 180 degrees.
Make 4 triangles and 2 squares using 6 straight lines?
Draw a rectangle in the ratio of 1:2 eg sides of 5cm & 10cm. Bisect both the longer sides and join their mid points with a straight line. Draw a diagonal. This gives you 2 squares, 2 big triangles and 2 small triangle (1 in each square)
What is an example of a scale factor?
If a big triangle has a base length of 6, and a small triangle has a corresponding base length of 3, the scale factor from large to small is 2/1 (or 2). The scale factor from small to large would be 1/2.
Show how to find scale factor of a small triangle to a larger similar triangle?
The ratio of the length of the side in the big triangle to the length of the corresponding side in the little triangle is the scale factor.
How do you find a scale factor from the smaller figure to the enlarged figure?
Look for corresponding parts of the two figures. Their ratio is the scale factor. For example, if you have two similar triangles, one has a side of length 3, and the corresponding side on the other triangle is 5, then the scale factor is 5/3 going from the small triangle to the big, or 3/5 going from the big triangle to the small.
How do you find the scale factor from a large rectangle to a small rectangle?
If you know one of the sides of both the rectangles than you just divide them by one another to find the scale factor.
What is true about the area of similar triangles when the sides are increased by the factor of two?
when you multiply the area of the small triangle by four it equals the area of the large triangle.
What is true about the area of similar triangles when the sides are increased by a factor of two?
When you multiple the area of the small triangle by four it equals the area of the large triangle.
How do you calculate the scale factor if you have the scale?
You calculate the scale factor if you do have a scale is by dividing if it is a small shape to a large shape and multiplying if it is a large shape to a small shape example: shape 1 sqaure shape 2 square equation 2 10 10/2=5 shape 2 square shape 2 square equation 10 2 2/10
Does weed dilate pupils?
no but i makes your pupils small and gives you bloodshot eyes
Small triangle is 52cm and large triangle is four ninths bigger what is it's size?
It is 4/9 of the small triangle plus the size of the small triangle
Does using heroin change the size of your pupils?
Well, they don't dilate, they become pinpoint. When pupils dilate, it means they get bigger.
How is the area of a triangle and parallelogram different?
They need not be. A bigger triangle can have the same area as a small parallelogram.They need not be. A bigger triangle can have the same area as a small parallelogram.They need not be. A bigger triangle can have the same area as a small parallelogram.They need not be. A bigger triangle can have the same area as a small parallelogram.
