Increasing the dimensions of the smaller of the similar triangles (if they are not already congruent) by a suitably chosen constant factor.
just use a scale factor! multiply all the dimensions by X and you'll have the dimensions of the new triangle. of course the angles and all are the same b.c theyre similar.
When you multiple the area of the small triangle by four it equals the area of the large triangle.
ratio
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.
Increasing the dimensions of the smaller of the similar triangles (if they are not already congruent) by a suitably chosen constant factor.
If two triangles are similar, then the reduced ratio of any two corresponding sides is called the scale factor of the similar triangles
Scale factor: 2 to 1

Similar triangles are two triangles with three identical angles but not necessarily identical lengths but if they aren't identical they must have an identical scale factor for each side. Congruent triangle have identical angles and lengths but mat be rotated. on a similar triangle if one size gets bigger by two times the original all of them must be two times the original.
the answer to this question is 1:4 10: ? =10x4/1 =40
Because if one triangle is an enlargement of another (with scale factor not 1) their angles will be the same but the sides will be different. The two triangles will be similar but not congruent.
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.
