Answer:

Because they're all have the same angles

Step-by-step explanation:

Triangles are similar to each other based on their angles. Two similar triangles have the same angles (in the same order).

Since equilateral angles all have 3 angles of 60 degrees... they're all similar to each other. The only variation is the length of their sides.

That's why you can't tell them apart! One for all, all for one!

Answer:

All equilateral triangles have 3 angles measuring 60 degrees.

Step-by-step explanation:

To get 2 triangles congruent, you must get 2 angles congruent. All equilateral triangles have 3 congruent angles, therefore all are similar.

Answer:

Step-by-step explanation:

The formula of a surface area of a cylinder:

$S.A.=2\pi r^2+2\pi rH$

r - radius

H - height

We have:

r = 5 in

H = 4 in

Substitute:

$S.A.=2\pi(5^2)+2\pi(5)(4)=2\pi(25)+2\pi(20)\\\\=50\pi+40\pi=90\pi\ in^2$

$\pi\approx\dfrac{22}{7}$

Substitute:

$S.A.\approx90\cdot\dfrac{22}{7}=\dfrac{1980}{7}\approx282.857\ in^2$

The image of the point (4, -9) under a translation is (9, -14). Find the coordinates

Answer:

(-4, -13)

Step-by-step explanation:

When the translation (T) is added, the image is formed.

(4, -9) +T = (9, -14)

T = (9, -14) -(4, -9) = (9-4, -14-(-9)) = (5, -5)

The same holds for the second point:

(-9, -8) +T = (-9, -8) +(5, -5) = (-9 +5, -8 -5) = (-4, -13)

The image of the second point under the same translation is (-4, -13).
