The least amount of information needed to establish congruence is; Angles M and M' are congruent, and angles N and N' are congruent.

<h3>What is the least amount of information needed to determine if the two triangles are similar?</h3>

If follows from concept of congruence that two triangles are congruent only if all three angle measures are congruent or all corresponding sides are in the same ratio.

Hence, when angles M, N and M', N' are established as congruent, it follows that the measures are equal respectively.

Ultimately, the measure of angles L and L' are equal and hence, all three angles are congruent in each triangle.

Therefore, the least amount of information needed is; Angles M and M' are congruent, and angles N and N' are congruent.

The graph of the quadratic parent function is reflected across the x-axis, then shifted 5 units down and 4 units right. Write th
vredina [299]

Answer:

  y = -(x -4)² -5

Step-by-step explanation:

-f(x) is a reflection of f(x) across the x-axis.

f(x) -5 is a translation down by 5 units.

f(x -4) is a translation right by 4 units.

Applying these transformations to y = x² gives, successively, ...

  y = -x²

  y = -x² -5

  y = -(x -4)² -5 . . . . . . the new equation in vertex form

WILL MARK BRAINLIEST!! Which of the following ordered pairs are y-intercepts? Check all that apply.
Y_Kistochka [10]
Y intercept is where the line meets the Y axis
So the points shd be in (0,y) form.

So (0,0) (0,-7) (0,-0.25) are the y-intercepts in the following.
