Determine whether one figure is a dilation of the other.

1 answer:

5 0

The answer is no.

A dilation is when a shape is scaled up or down to create a similar shape. The only thing that changes is the lengths of the sides. The angles will stay the same.

In this case, the original has angles 54, 29, and 97.

After the transformation the triangle has the angles 29, 59, and 92.

Answer:

5cm wide, 10cm long.

Step-by-step explanation:

I came to this answer by looking for common factors between 50 and 5, and I found 10.

5cm + 5cm = 10cm, so it works.

To confirm this, I multiplied 5 and 10 and got 50cm (squared) which works.
