Q: At which angle will the hexagon rotate so that it maps onto itself?

hexagon will onto at an angle of 60°. Explanation A hexagon has rotational symmetry of order6, meaning it maps onto itself after rotations of multiples $60°$ (since $360°/6 60°$). These rotations include $60° $120°$, $° $°$, $300°$, and $0°$ (a full rotation: Recognize that a regularagon has identical sides and. The symmetry rotations are spaced around the circle, dividing $360°$ into 6 parts. Therefore, the smallest non-zero angle for which the hexagon maps onto itself is $60°$. Hence, the hexagon will map itself when rotated by 60°$.

Q: The graph shows the four quadrants of the coordinate plane.An XY coordinate plane divided into four quadrants. The x axis runs from left to right. The y axis runs up and down. Quadrant 1 is the top right quadrant. Quadrant 2 is the top left quadrant. Quadrant 3 is the bottom left quadrant. Quadrant 4 is the bottom right quadrant. y x Quadrant I Quadrant II Quadrant III Quadrant IV Where is (−2.5,2) located on the coordinate plane?Choose 1 answer:Choose 1 answer:(Choice A) Quadrant I AQuadrant I (Choice B) Quadrant II BQuadrant II (Choice C) Quadrant III CQuadrant III (Choice D) Quadrant IV DQuadrant IV (Choice E) x -axisE x -axis(Choice F) y -axisF y -axis18 of 22

The correct answer is: Choice B Quadr II. **Explanation point $(-2.5, 2)$ has a negative x-coordinate and a positive y-coordinate. In the coordinate plane, Quadrant II contains points where the x-value is negative and the y-value is positive. Therefore, $(-2., 2)$ located in Quadrant II. Steps: The x-coordinate $-2.5$, is less than zero, the point is to the left of y-axis. The-coordinate is $2\ which is greater than zero, indicating the point is above the x. 3. Combining, the point is in the top-left section of the plane, which isant II. Hence, the point \((-2., 2)$ is in Quadrant II.

Q: What is the value of x?

I need information or the specific equation to determine value of $$. Please provide the complete problem or.

Question

Pedro is going to use SAS to prove that ΔPQR ≅ ΔSQR. Which of these is a necessary step in Pedro's proof? A. Prove that ∠QPR ≅ ∠QSR by the Isosceles Triangle Theorem. B. Prove that QR ≅ QR by the reflexive property. C. Prove that PQ ≅ SQ by CPCTC. D. Prove that ∠PQR ≅ ∠SQR by vertical angles.

Accepted Answer

The correct answer is B.

Explanation

To use SAS you need two pairs of corresponding sides and the included angle between them. A common and necessary step is to note the shared side:

QR ≅ QR (reflexive property).

Why the others are wrong:
A: The Isosceles Triangle Theorem applies only if you already know a triangle is isosceles; nothing in the statement guarantees that, so it’s not a necessary step.
C: CPCTC (corresponding parts of congruent triangles are congruent) can only be used after the triangles are proven congruent — you cannot use it to prove congruence.
D: ∠PQR and ∠SQR are adjacent angles that share side QR, not vertical angles, so you cannot claim they’re equal by the vertical-angles theorem.

Therefore showing QR ≅ QR by the reflexive property is a necessary step for a SAS proof.
