A student claimed that reflect a triangle in a line, translating a triangle , rotating a triangle, and reflecting it in a point
Nady [450]

If we reflect a triangle in a line, translate a triangle, rotate a triangle, and reflect it in a point result in an image that will be congruent to the original( pre-image) triangle.

This is a problem from triangular geometry. We can solve this problem by following a few steps.

Here a triangle ABC is given and the triangle is at first reflected and then translated, thereafter it rotates and is later reflected.

After all, these processes the value of ∠A, ∠B, and ∠ C remains the same as usual concerning ∠A''', ∠B''', ∠ and C'', as they just changes coordinates not geometric structures.

After all these processes the length of the triangle AB, AC, BD, and A'''B''', B'''C''', C'''A''' remains the same as usual.

∵ We can conclude that ΔABC ≅ ΔA'''B'''C'''

( As AB = A'''B''', BC = B'''C''', ∠ABC = ∠ A'''B'''C''' )

Identify the graph as eIdentify the graph as either y = cos x  or y = sin x
serious [3.7K]
From the graph at x = 0, y = 0


Check1:
y = cosx

0 = cos(0)
0 = 1

therefore, this is not the function

Check2:
y = sinx
0 = sin(0)
0 = 0

therefore, this is the function


Conclusion:

the function in the graph is y = sinx

Andreyy89

Answer:

Step-by-step explanation:

Hey, hope you're having a great day. :)

The floor of the round hut suggests that this is a cylinder, so.

Lets assess the formula.

A = 3.14 x r^2

A = 3.14 x 2^2

A = 3.14 x 4

A = 12.56.

Hope this helps!

2x + y = -4<br> 2x + 3y = 4
kirill115 [55]

Answer: x=4 ; y=<u> -4</u>

                            3

Step-by-step explanation:

2x + y = -4 .(-3)

2x + 3y = 4

-6x-3y=12

<u>2x + 3y = 4</u>

4x=16

x= <u>16</u>

    4

x=4

2x + 3y = 4

2.4+3y=4

8+3y=4

3y= -8+4

y=<u> -4</u>
