Answer:

Step-by-step explanation:

Symmetry is when you can flip the figure over a line and it will perfectly match the other side.

We see that if we draw a vertical line down the middle and a horizontal line across the middle, we get mirror images. So that's 2.

Then notice that we can draw two diagonals across the image, one from the upper left corner to the lower right corner and the other from the upper right corner to the lower left corner. That's another 2.

We try to find more, but try as we might, there are no others to be found.

Thus, there are 4 lines of symmetry.

Hope this helps!

4. A triangle has vertices A(4, 2), B(3, 7), and C(–4, –5).

Alex

To draw the median of the triangle from vertex A, the mid point of BC must be determined. The median of the vertex A is given at (-1/2, 1). See explanation below.

<h3>How you would draw the median of the triangle from vertex A?</h3>

Recall that B = (3, 7)

and C = (-4, -5).

Note that when you are given coordinates in the format above, B or C = (x, y)
Hence the mid point of line BC is point D₁ which is derived as:
D₁ $[ (\frac{3-4}{2})$ , $(\frac{7-5}{2}) ]$
hence, the Median of the Vertex A = (-1/2, 1).
