Answer:

The characteristics of a good math explanation are following:

1. Step by step explanation: The first characteristics of a good math explanation is step by step solution. Do not skip steps because the assumption that the other person knows what you did is not always correct.

2. Justify each step: Mention the reasons behind each step, i.e, theorem, formula, rule etc.

3. Result verification: After find the solution the last step is to verify the solution.

We need to check whether the solution fulfills the given conditions or not. If it satisfy all the given conditions, then it is correct otherwise we need to check our work.

Answer:

WXYZ can not be a rectangle because consecutive sides are not perpendicular to each other.

Step-by-step explanation:

The given vertices are W(-4,3), X(1,5), Y(3,1) and Z(-2,-1).

Plot these points on coordinate plane and draw the quadrilateral as shown below.

$Slope=\dfrac{y_2-y_1}{x_2-x_1}$

Using this formula, we get

$m_{WX}=\dfrac{5-3}{1-(-4)}=\dfrac{2}{5}$

$m_{XY}=\dfrac{1-5}{3-1}=\dfrac{-4}{2}=-2$

Now,

$m_{WX}\times =\dfrac{2}{5}\times (-2)=-\dfrac{4}{5}\neq -1$

Here, WX and XY are two consecutive sides of quadrilateral but the product of their slopes is not equal to -1. It means they are not perpendicular to each other.

Since, all interior angles of a rectangle are right angles, therefore, WXYZ can not be a rectangle.

Ames wants to informally prove the converse of the Pythagorean Theorem by producing some evidence that supports it.

Mazyrski [523]

Answer:

The second and fourth one is right

Step-by-step explanation:

A²+ B² = C²

15² + 20² = 25²

225 + 400 = 625

625 = 625

16² + 30² = 34²

256 + 900 = 1156

1156 = 1156
