State of the triangles in each pair of similar. if so, state how you know they are similar and complete the similarity statement.

Step-by-step explanation:

The vertical angles at A are the same. The angles at B and F are marked the same. So each triangle has two angles in common with the other. That is all that is required for AA similarity.

Vertex A corresponds to itself, vertex A.

Vertex B corresponds to vertex F, since that is where the angles are marked the same.

The remaining vertices are C and G, and they correspond to each other.

Hence, the corresponding vertices (in the same order) are ... ABC and AFG. This is how the similar triangles are named:

  ΔABC ~ ΔAFG

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.
