How to find which triangle which triangle is the reflection of triangle 1 over the line y=x?
- If a triangle is reflected over the line y=x, then the coordinates of the vertices of the triangle gets interchanged.
In the given figure the vertices of the triangle are (1,1) , (4,1) and ( 4,3)
So, after reflection over the line y=x,
- The vertices of the triangle will be (1,1) , ( 1,4) and (3,4).
- Clearly, the triangle will be in the first quadrant itself
So, the correct answer will be option A , where the triangle has the vertices (1,1) , ( 1,4) and (3,4).
- In other options the triangles are not even in the first quadrant.
