Which type of triangle will always have at least 1 -fold reflectional symmetry? right triangle obtuse triangle acute triangle isosceles triangle

Isosceles triangles are the champions of reflectional symmetry! No matter what, they will always have at least one line of symmetry that runs down the height, splitting the triangle into two equal halves. This makes them look elegant and balanced, a perfect reflection of their name! On the flip side, right triangles, obtuse triangles, and acute triangles may not always boast this symmetrical flair. While some of them could have neat properties in specific cases (like certain right triangles), they're often asymmetrical and do not guarantee that lovely fold of symmetry found in isosceles triangles. So, if you're looking for a triangle that’s always symmetric, isosceles is your go-to!
