Below represents the proof that the quadrilateral QRST is a parallelogram
<h3>How to prove that QRST is a parallelogram?</h3>
The coordinates are given as:
Q = (-1,-1)
R = (2,9)
S = (-4,5)
T = (-7,-5)
Calculate the length of each side using:

So, we have:




The above computations show that opposite sides are equal.
Next, we determine the slope of each side using:

So, we have:




The above computations show that opposite sides are parallel, because they have equal slope
Hence, the quadrilateral QRST is a parallelogram

Answer:
1:6
Step-by-step explanation:
Given that there are 10 circles and 2 triangles, the total number of shapes is equal to 10+2.
10+2=12
Because there are 2 triangles, the ratio of triangles to total shapes is equal to 2:12.
However, this ratio can be simplified because both sides are multiples of 2. Divide both sides of the ratio by 2 to simplify the ratio.
2:12
1:6
Therefore, the simplest ratio of triangles to total shapes is 1:6.
I hope this helps!
