What two congruent triangles share the side AC?

forsale [732]

The two congruent triangles that share the side AC are (c) △ADC and △CFA

<h3>How to determine the congruent triangles?</h3>

For two triangles to share the sides AC, then the points A and C must appear on the names of the triangles

In option (c), we have A and C in the names of the triangles ADC and CFA

Hence, the two congruent triangles that share the side AC are (c) △ADC and △CFA

Write the domain and range as inequalities.

Andrews [41]

Answer:

domain: -∞ < x < ∞
range: -2 ≤ y < ∞

Step-by-step explanation:

<u>Domain</u>

The domain is the horizontal extent of the function, the set of input values for which it is defined. A parabola that opens up or down is defined for all x values, so its domain is ...

-∞ < x < ∞ . . . . . . (-∞, ∞) in interval notation

__

<u>Range</u>

The range is the vertical extent of the function, the set of output values it produces. The vertex of the parabola is one extreme of the range. Depending on the direction it opens, the other extreme will be +∞ or -∞. The range includes the y-value of the vertex. Here, the range is ...

-2 ≤ y < ∞ . . . . . . [-2, ∞) in interval notation

(50 POINTS) The figure is transformed as shown in the diagram. Describe the transformation. A) dilation, then reflection B) refl

Helga [31]

Answer:

Hi there I was just working on this question on UsaTestPrep and idk if the answer is really correct but here: C: reflection then rotation.

Step-by-step explanation:

Extra Info:

Dilation is when the shape changes in size, which doesn't happen.

Translation is when it just moves across. It may look like that is happening here, but I'll explain.

The triangle is first reflected along the line . Imaging putting a mirror on the x=0 line (the y axis, basically), and you'd see 1 to 2.

Then, it is rotated around the point . Get a bit of tracing paper, draw over 2, and then, holding the tracing paper down at (works well with a pencil), rotate it round and you will find it fits perfectly over 3.

Also is this the diagram?
