How many non-congruent triangles can be formed by connecting 3 of the vertices of the cube?

alexira [117]

Answer:

The number of non-congruent triangles that can be formed by connecting 3 of the vertices of the cube is 3 non-congruent triangles

Step-by-step explanation:

From the three dimensional shape of a cube, triangles can be constructed from;

1) 6 side faces

2) 4 front face to opposite vertices triangles

3) 4 rear face to opposite vertices triangles

Each face can produce ₄C₃ = 4 triangles

Therefore;

The total number of triangles that can be formed = 4 × 6 + 4 × 4 + 4 × 4 = 56 triangles

Of the 56 triangles, it will be found that all 24 triangles from the different 6 direct faces will have the same dimension of 1, 1, √2 are congruent

The 24 triangles formed by the sides of the faces and an adjacent diagonal have the same dimension of 1, √2, √3 and are congruent

The 8 triangles formed by joining the three diagonals have the same dimension of √2, √2, √2 are congruent

Therefore, the 56 triangles comprises of a combination of three non-congruent triangle.

There are only 3 observed non congruent triangles formed by connecting three of the vertices of the cube.

What is the equation of the line that is perpendicular to the like y=-4x + 7 and passes through the point (8,2)?

Nookie1986 [14]

Answer:

$y=\frac{1}{4}x$

Step-by-step explanation:

Given equation of line:

$y=-4x+7$

To find the equation of line perpendicular to the line of the given equation and passes through point (8,2).

Applying slope relationship between perpendicular lines.

$m_1=-\frac{1}{m_2}$

where $m_1$ and $m_2$ are slopes of perpendicular lines.

For the given equation in the form $y=mx+b$ the slope $m_2$ can be found by comparing $y=-4x+3$ with standard form.

∴ $m_2=-4$

Thus slope of line perpendicular to this line $m_1$ would be given as:

$m_1=-\frac{1}{-4}$

∴ $m_1=\frac{1}{4}$

The line passes through point (8,2)

Using point slope form:

$y_-y_1=m(x_-x_1)$

Where $(x_1,y_1)\rightarrow (8,2)$ and $m=m_1=\frac{1}{4}$

So,

$y-2=\frac{1}{4}(x-8)$

Using distribution.

$y-2=(\frac{1}{4}x)-(\frac{1}{4}\times 8)$

$y-2=\frac{1}{4}x-2$

Adding 2 to both sides.

$y-2+2=\frac{1}{4}x-2+2$

$y=\frac{1}{4}x$

Thus the equation of line in standard form is given by:

$y=\frac{1}{4}x$
