Question
Graph the reflection of the polygon in the given line: y = x
Hint:
Plot the given vertices of a triangle on the graph and then obtain the points of reflection.
The correct answer is:
* In Geometry, a reflection is known as a flip. A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection.
*It is a type of transformation that produces mirror image of the shape.
The reflection transformation can be done in many ways.
*Reflection over X-axis
*Reflection over Y-axis
*Reflection over Y = X
Given That:
>>>Let (a, b) be a point in the x-y plane then the point of reflection with respect to y=x becomes (b, a).
>>>Then, the points of reflection for the vertices of the triangle are A(-6,-4);B'(-5,-1);C'(-3,-2) becomes:
A'(-4,-6); B'(-1,-5); C'(-2,-3).
>>>The required graph is:
If (a, b) is reflected in the line y = x, its image is the point (b, a).
(a, b) → (b, a)
A (-6, -4) → (-4, -6)
B (-5, -1) → ( -1, -5)
C (-3, -2) → (-2, -3)

The vertices of a triangle are A (2,3), B (6,1) and C (7,5). Graph the reflection of the triangle ABC in the line x = 3.
The result of flipping a triangle on a line of reflection based on a coordinate system is a figure known as a triangle reflection. Therefore, it's crucial to understand the following terminology when researching and working on the reflection of polygons, such as the triangle:
Pre-image: The primary image, in this case, is a triangle, which is reflected across a line.
Image: The triangle being reflected and the result after being reflected again. To reflect a triangle, you must first reflect the three points that make up each triangle over the line of reflection and then use the algebraic reflection properties on each coordinate.
¶In a triangle reflection, the pre-point image and the image's point are at the same distance from the line of reflection. Something is one method of doing this correctly.
