Suppose that and are corresponding sides of similar triangles If AB 6 and the scale factor is 3 what is EF?

I assume the corresponding sides are AB and EF, and EF is a side of the larger (second) triangle.
scale factor 3 means each length of the second is 3 times as long as the first.
⇒ if AB = 6 units, EF = 3 x 6 units = 18 units.

What is a scale factor on a triangle?
If two triangles are similar, then the reduced ratio of any two corresponding sides is called the scale factor of the similar triangles
How do you find a scale factor of a triangle?
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.
What is the ratio of 2 corresponding linear measurements in a pair of similar figures?
The constant of proportionality or scale factor.
What is the scale factor of 0.8?
When two similar shapes have a scale factor of 0.8, every length of the second is 0.8 times the corresponding length of the first.
What is the scale factor of the perimeters of triangle ABC and triangle WXY?
APPLYING THE SCALE FACTOR OF SIMILAR TRIANGLES TO THE PERIMETER The scale factor of two similar triangles (or any geometric shape, for that matter) is the ratio between two corresponding sides. In today's lesson, we will show that this same scale factor also applies to the ratio of the two triangles' perimeter. This is fairly easy to show, so today's lesson will be short. PROBLEM Two triangles, ΔABC and ΔADE are similar, ΔABC∼ ΔADE. The scale factor, AB/AD is 6/5. Find the ratio of the perimeters of the two triangles. Similar triangles in geometry STRATEGY We will use the definition of the scale factor to define one set of sides in terms of the other set of sides, Then, apply the definition of the perimeter. and write out the perimeter of both triangles using one set of sides. SOLUTION (1) ΔABC∼ ΔADE //Given (2) AB/AD = 6/5 //Given (3) BC/DE = 6/5 //(1), (2), scale factor is the same for all sides in similar triangles. (4) AC/AE = 6/5 //(1), (2), scale factor is the same for all sides in similar triangles. (5) AB = 6/5*AD // rearrange (2) (6) BC = 6/5*DE // rearrange (3) (7) AC = 6/5*AE // rearrange (4) (8) PABC=AB+BC+AC //definition of perimeter (9) PADE=AD+DE+AE //definition of perimeter (10)PABC=6/5AD+6/5DE+ 6/5*AE //(8), (5), (6) , (7), Transitive property of equality (11)PABC=6/5*(AD+DE+AE) //(10), Distributive property of multiplication (12) PABC=6/5*PADE //(11), (9), Transitive property of equality (13) PABC/PADE=6/5 And so we have easily shown that the scale factor of similar triangles is the same for the perimeters.

The what of the corresponding side lengths of similar triangles is called the scale factor?
ratio
Who can help with this The corresponding side lengths of similar triangles are related through multiplication by the factor.?
It is true.
Are the ratios of all three pairs of corresponding sides of similar triangles equal?
Yes. When a shape is enlarged the scale factor gives the ratio between corresponding lengths of the enlargement and the original.
Similar triangles can be made into congruent triangles by doing what?
Increasing the dimensions of the smaller of the similar triangles (if they are not already congruent) by a suitably chosen constant 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.
What are similar solids?
similar shapes have corresponding angles that are equal. Also, any length in one shape is equal to the scale factor times the corresponding length in the other shape.
How do you find scale factor of similar objects?
Assuming you are already sure that the two objects are, indeed, similar: You measure corresponding lengths of the two objects, and divide.You measure the lengths of a pair of corresponding sides. The scale factor is the ratio of the two measures.
How do you find a scale factor of a triangle?
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.
The corresponding side lengths of similar triangles are related through multiplication by the factor?
The sum of the squares of the two smaller sides (the two sides adjoining the right angle) is equal to the square of the longest side - which is called the hypotenuse. This result is Pythagoras's Theorem.
What is the ratio of any two corresponding lengths in two similar geometric figures?
