length
What is the scale factor of the dilation that transforms triangle PQR to triangle P'Q'R' explain your answer?
The scale factor of the dilation that transforms triangle PQR to triangle P'Q'R' can be determined by comparing the lengths of corresponding sides of the triangles. If, for example, the length of side PQ is 4 units and the length of side P'Q' is 8 units, the scale factor would be 8/4 = 2. This means that triangle P'Q' is twice the size of triangle PQR, indicating a dilation with a scale factor of 2.
What happens when you dilate a triangle with a scale factor of 2?
When you dilate a triangle with a scale factor of 2, each vertex of the triangle moves away from the center of dilation, doubling the distance from that point. As a result, the new triangle retains the same shape and angles as the original triangle but has sides that are twice as long. This means the area of the dilated triangle becomes four times larger than the original triangle's area.
What is center of gravity of a triangle?
The center of gravity of a triangle is its centroid. The centroid of a triangle is the intersection of the three medians.
Does dilation change the shape?
Geometric dilation (size change, typically expansion) does not change the shape of a figure, or its center location, only the size.
Triangle ABC below will be dilated with the origin as the center of dilation and scale factor of 1/2?
0.5
If Triangle R'S'T' has sides of 3 cm 4 cm and 5 cm. And triangle RST has sides of 12 cm 16 cm and 25 cm. what is the dilation of the triangles?
The 1st is a right angle triangle and the 2nd is a scalene triangle.
Every dilation has a?
Center and Scale Factor....
The center of gravity of a triangle solid with uniform thickness and density is at the intersection of the of the triangle?
The center of gravity of a triangle can be found by adjusting the thickness. You also need to find the density at the intersection.

A photographer knows that the center of a camera lens acts as a center of dilation, where the image of an object forms behind the lens.Is the scale factor for this dilation negative or positive?
Negative
What are the coordinates of the vertices of triangle a'b'c' after triangle ABC is dilated using a scaling factor of 3?

When applied to a triangle a dilation with a positive scale factor does not preserve to what?
The perimeter to area ratio.
How do you find the in-center of a triangle?
To find the incenter of a triangle, you bisect two or more of the angles. The one spot where these two or more angles meet is called the incenter.
