Answer:

(E) 90°

Step-by-step explanation:

The diagonals of a parallelogram are equal in length if and only if the parallelogram is a rectangle.

Any angle of a rectangle is 90°.

_____

Adjacent angles of a parallelogram are supplementary. If the diagonals are the same length, the triangles formed by either diagonal are congruent with the triangles formed by the other diagonal. This means adjacent angles are congruent. Congruent supplementary angles are 90°.

Answer:

a) true

Step-by-step explanation:

The bottom-line numbers from synthetic division <em>alternate signs</em>, indicating that -2 is a lower bound. The given statement is true.

If the signs were all positive, it would indicate the proposed zero is an <em>upper bound</em>.

Answer:

Part A :

The scale factor of the dilation that transforms triangle PQR to triangle P'Q'R' is divided by 3.

Part B :

P"(-1,2), Q"(0,3), R"(1,0)

Part C :

Triangle PQR and P"Q"R" are not congruent because congruent means equal and similar but triangle PQR and P"Q"R" are proportional because they are rational to each other but do not have the same measures of sides but the angles are congruent.

This is the graphing of the triangle.
