which sketch is equiangular, but not equilateral?
a a
b b
c c
d d

Explanation:

1. Equiangular definition: All internal angles are equal.
2. Equilateral definition: All sides are equal in length.
3. Analyze Option A: The shape is a rectangle, where all angles are 90° (equiangular), but its length and width are different (not equilateral).
4. Analyze Option B: The triangle has two equal base angles but a different vertex angle, so it is not equiangular.
5. Analyze Option C: The cross shape has angles of different measures, so it is not equiangular.
6. Analyze Option D: The octagon has all angles equal and all sides marked as equal, so it is both equiangular and equilateral.

Answer:

A. A
