Question

HELP HELP--Given an equilateral triangle, what kind of symmetry will the figure have: point, line, plane. (Select all that apply.)

Answer 1

line and point

Explanation:

a triangle can be equally split in half, as well as with a point in the middle

Answer 2

• line symmetry
• rotational symmetry about a point (centroid)

Explanation:

An equilateral triangle has rotational symmetry about its centroid (point). There does not exist a point such that the reflection of the figure across the point is the same as the figure.

It has mirror symmetry about any altitude line.
