Confused: Do you mean the white part of the eyes? Are they red and irritated? The sclera is generically referred to as the white of the eye, made of a very tough type of protein. When it becomes red,  the causes can vary; from infection, to eye pressure, to injury, dryness of the cornea, allergy, etc. While some causes may be self-limited, others could blind you.
Given that triangle CDE is translated down and to the right, forming triangle C'D'E'. Therefore, the congruency statement that is correct is Î´DCE â Î´D'C'E'.
In a previous post, I made this mistake when discussing right triangles on the Giant Pegboard. If a mathematician can make the error, then it is easy for a kid to, also. In the video I said âcongruentâ when I meant âsimilar.â Two triangles are congruent if they are the same size and shape. They are similar if they are the same shape (and maybe or maybe not the same size). One way to show that two triangles are congruent is to use the SSS Theorem or the âside side sideâ theorem.
