Dilation - the image created is not congruent to the pre-image
No, congruent triangles are always similar but similar triangles and not always congruent. Imagine that similar triangles can be created on a copy machine enlarge and shrink the image, turn it, even turn it over, the angles remain the same. A congruent triangle must be exactly the same as the original. Hope this helps!
opposite sides are congruent corresponding parts of congruent triangles are congruent(apex)
think a congruent sign with a slash through it.
= with a ~ on top of it ~ = ≅
= with a ~ on top of it ~ = ≅
the symbol for congruent is ~ with _ in the same space. (US keyboard does not have a congruent key
it is the equal sign = with the symbol ~ over it
Three vertical parallel lines: |
copy and paste this ≅
= congruent sign
It's the equals sign with the ~ above it. ≅
From the upper toolbar pick: Insert - Symbol Then just search until you find what you need.
"Congruent to" is usually referring to shapes in Euclidean geometry and proofs, hence it is written out. If one is talking about "congruences", as in elementary number theory, then the symbol looks like an equal sign, except there is three instead of two lines.
Drawing two tiny parallel lines over the segment will indicate that it is a congruent segment. The little arc symbol can also be drawn over the segment or the angles.
