Given any triangle in the plane, associate to each side an outward pointing normal vector of the same length as the side. Show t

Zigmanuir [339]

Let , a, b and c be the length of three sides of triangle, represented in terms of vectors as $\vec{a},\vec{b},\vec{c}$ .

Now, vector of same Magnitude acts as normal vector to each side.

So, equation of any vector p having normal q is given by

$\vec{p} \times\vec{q}$

Now sum of three vector and it's normal is given as

$=\vec{a} \times\vec{a}+\vec{b} \times\vec{b}+\vec{c} \times\vec{c}\\\\=0+0+0\\\\=0$

Cross product of two identical vectors is Zero.

$\rightarrow \vec{i} \times\vec{i}=0$

Which statement best explains whether △ABC is similar to △DEF?

Sati [7]

A). They are not similar, because 6/13 is not equal to 8/20

For triangles to be similar, the ratios of sides need to be the same (shortest to shortest, middle to middle, longest to longest). The shortest sides are 6 and 13, respectively, the middle ones are 8 and 20. Because 6/13 is not equal to 8/20, the triangles are not similar.

Can someone please help me with this math question

lora16 [44]

Answer:

C'(4,4)

Step-by-step explanation:

The dilation of quadrilateral ABCD over the origin by a scale factor of 2 has the rule

(x,y)→(2x,2y)

So,

A(-3,-1)→A'(-6,-2)
B(-1,1)→B'(-2,2)
C(2,2)→C'(4,4)
D(3,-2)→D'(6,-4)

Hence, the coordinates of the image point C' are (4,4) (see attached diagram for details)
