Question
**Reflection in Geometry** ### Problem 13: **Reflect the triangle with vertices:** - (-19, -11) - (11, -19) - (-10, -17) **over the y-axis.** Reflection over the y-axis involves changing the sign of the x-coordinates of each vertex without altering the y-coordinates. For example: - The point (-19, -11) reflects to (19, -11). - The point (11, -19) reflects to (-11, -19). - The point (-10, -17) reflects to (10, -17). The new coordinates of the triangle after reflection over the y-axis will be: - (19, -11) - (-11, -19) - (10, -17) This process ensures that the triangle is mirrored across the y-axis, maintaining its shape and size but flipping it horizontally.
