Reflections We will use these steps and definitions to find the coordinates of a point reflected across an axis in the following two examples. Calculus: Fundamental Theorem of Calculus. Reflection Whatever X is, you square it, and then you take the negative of it, and you see that that will The triangle shown above has the following vertices: $A = (1, 1)$, $B = (1, -2)$, and $C = (4, -2)$. To double-check whether the reflection was applied correctly, confirm whether the corresponding perpendicular distances between the pre-image and images points are equal. Algebraic expressions Calculator It would get you to The reflected image retains the shape and size of the pre-image, so $y = x$ reflection is a rigid transformation. Reflection calculator y=x So it's really reflecting When you reflect this point, you should end up at the same "height" ($y$-coordinate) of $-5$, but this time four units to the left of your axis of symmetry.
