The line is drawn at point A and Point C is a line of symmetry because lines of symmetry make exactly two halves with similar shapes and sizes.
<h3>What is a line of symmetry?</h3>
It is defined as the line which will make exactly two halves with similar shape and size in geometry. For a two-dimensional shape, there is a line of symmetry, and for three-dimensional shapes, there is a plane of symmetry. In other words, if we make a mirror image of the shape around the line of symmetry, we will get exactly the same half portion.
We have given a figure in the picture.
The figure is a quadrilateral(a kite)
As we know, lines of symmetry make exactly two halves with similar shapes and sizes.
IF we draw a line from Point A to Point C we will get two similar and figures in size and shape.
Thus, the line is drawn point A and Point C is a line of symmetry because lines of symmetry make exactly two halves with similar shapes and sizes.

BY the AA postulate, triangles ABC and APQ are similar.
In similar triangles, corresponding sides are proportional.
This means that
AB/AP = BC/PQ
Substituting values,
AB=15
AP=15+7.5=22.5
PQ=18
=>
15/22.5 = x / 18
solve for x
x=18(15/22.5)=18(2/3)=12
Answer: x=12
The formula for A = Ao (1/2) ^ t/h
So sub in.
