I need some help with this question.
zysi [14]

The scale factor will be 1.5. The corresponding angles are congruent because the size is changed not the angles.

<h3>What is dilation?</h3>

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

Adnan wants a larger garden.

He draws the triangle ΔPQR to show his original garden.

He wants to enlarge a garden, so he uses a dilation to form the image of the triangle ΔPQ'R'.

He uses vertex P as the center of the dilation.

The ratio of the corresponding sides will be given as

PQ'/PQ = Q'R'/QR = R'P/RP = 1.5

The scale factor will be 1.5.

The corresponding angles are congruent because the size is changed not the angles.

More about the dilation link is given below.

Which proportion correctly shows the equivalence of two fractions?
lyudmila [28]

Answer:

B is your answer.

Step-by-step explanation:
