On a piece of graph paper, plot the following points: A (0, 0), B (5, 0), and C (2, 4). These coordinates will be the vertices o
shtirl [24]

The triangle is an isosceles triangle and the four triangles are similar

<h3>How to determine the triangle type?</h3>

The coordinates are given as:

A (0, 0), B (5, 0), and C (2, 4).

Calculate the distance between the coordinates using:

d = \sqrt{(x_2 -x_1)^2 +(y_2 -y_1)^2

So, we have:

AB = \sqrt{(0 -5)^2 +(0-0)^2} =5

AC = \sqrt{(0 -2)^2 +(0-4)^2} =4.5

BC = \sqrt{(5 -2)^2 +(0-4)^2} =5

The above shows that two sides are congruent.

Hence, the triangle is an isosceles triangle

<h3>The midpoints of the sides</h3>

This is calculated using:

(x, y) = 0.5 * (x1 + x2, y1 + y2)

So, we have:

AB = 0.5 * (0 + 5, 0 + 0) = (2.5, 0)

AC = 0.5 * (0 + 2, 0 + 4) = (1, 2)

BC = 0.5 * (5 + 2, 0 + 4) = (3.5, 2)

From the attached graph, we can see that the triangles are similar

3.25, 3.0, 2.75, 2.5, 2.25, ...
Morgarella [4.7K]
3.25 - 3 = 0.25
3 - 2.75 = 0.25
2.75 - 2.5 = 0.25
2.5 - 2.25 = 0.25

Since we subtracted those numbers, it means we are decreasing.
Therefore, the answer is decrease by 0.25.
