A triangle, ΔABD, is reflected across the line y = x to have the image ΔA'B'D' in the standard (x, y) coordinate plane: thus A reflects to A'. The coordinates of point A are (m, n). What are the coordinates of point A'?
  • a)
    (-m, n)
  • b)
    (m, -n)
  • c)
    (-m, -n)
  • d)
    (n, m)
  • e)
    Cannot be determined from the given information.

The correct answer is d. The image of a point (x, y) reflected across the line y = x will have coordinates (y, x). If the coordinates of point A are (m, n), then the coordinates of point A' are (n, m).

In geometry, is a polygon with three sides and three angles. The sum of the three interior angles of a triangle is always 180 degrees.Triangles can be classified based on their side lengths and angles. Types of triangles based on side lengths include equilateral (all sides are equal in length), isosceles (two sides are equal in length), and scalene (no sides are equal in length). Types of triangles based on angles include acute (all angles are less than 90 degrees), right (one angle is 90 degrees), and obtuse (one angle is greater than 90 degrees).Triangles are commonly used in various mathematical problems and real-world applications, such as in architecture, engineering, and navigation.
