Answer:

A. When its sides are congruent

Step-by-step explanation:

By definition a square is a four sided polygon (shape) which has four right angles and four sides of equal length.

So, when a rectangle has all congruent sides, its a square because its a rectangle so it has four right angles, and congruent sides are sides of the same length.

B is incorrect because a rectangle can have four right angles but have differing side lengths

C is incorrect because again a rectangle can have parallel sides but have differing side lengths

D is incorrect because it can have convex angles but again have differing side lengths

True or False? An isosceles triangle can be scalene. A. True B. False

False. An isosceles has is defined by its two equal sides, scalenes do NOT have any equal sides.

Quadrilateral PQRS, with vertex P(-5, -3), undergoes a transformation to form quadrilateral P′Q′R′S′, with P′ at (5, 3). The typ

Answer:

D. 180 degrees about the origin.

Step-by-step explanation:

Let's consider what these transformation choices do.

A. Reflection over the X-axis changes the sign of the Y-coordinate. (-5, -3) becomes (-5, 3).

B. Reflection over the Y-axis changes the sign of the X-coordinate. (-5, -3) becomes (5, -3).

Reflection over both axes changes the signs of both X- and Y-coordinates, so (-5, -3) would become (5, 3). That is, one choice for the desired transformation is "A and B".

C. Translation 2 right and 7 up adds (2, 7) to the coordinates, so (-5, -3) becomes (-3, 4).

D. Rotation 180° about the origin changes the signs of both X- and Y-coordinates, so (-5, -3) becomes (5, 3). This is an appropriate single choice for the desired transformation.
