Question 9 of 10
harkovskaia [24]

Out of the two parallelograms shown, we can say that A. Both I and II; congruent diagonals property.

<h3>Which of the shapes is a rectangle?</h3>

Rectangles can be proven to be rectangles by the congruent diagonals property.

This states that rectangles should be able to have diagonal lines extending from all sides within the rectangle that are perpendicular to each other.

These lines should bisect each other. As shown in the daigram, both shapes have that quality and so are both rectangles.

Can someone solve this?
Gemiola [76]

Answer:

B : 4x\sqrt{17}

Step-by-step explanation:

If you divide a rhombus using its diagonals, you get 4 right triangles, whose legs are both 1/2 the length of the diagonals.

This means that the legs of one of those 4 triangles have lengths of 2x/2, and 8x/2, so the legs of one of those triangles x and 4x. This makes the length of one side equal to \sqrt{x^{2} + (4x)^{2}} = \sqrt{17x^2} = x\sqrt{17}. Because all 4 sides are the same length, you multiply this value by 4, and get 4x\sqrt{17}, which is B.
