No.
Both have at least one hexagonal face (base). Both have six faces that are topologically equivalent (either rectangles, or triangles).
they both have straight edges
Both are different triangles.
Both of their bases are rectangles, and they are both 3D.
There are both golden triangles and golden rectangles. In order to be considered golden the ratio must be the same as the sum of the longest side to the other two sides.
they are both triangles (3 sides)
No because they are both different types of triangles
Because they are both triangles and they are both 3 dimensional!
Thy both have three angles.
Both a triangle and a pyramid have three sides and three vertices in their simplest forms. A triangle, as a two-dimensional shape, consists of three straight sides and angles, while a pyramid is a three-dimensional shape that has a triangular base and triangular faces that meet at a single apex. Additionally, both shapes can be categorized based on their angles and sides—triangles can be classified as acute, obtuse, or right, and pyramids can be regular or irregular based on their base shapes. Both structures also exhibit geometric properties such as perimeter and area for triangles, and surface area and volume for pyramids.
An equilateral triangle and an isosceles triangle would both have lines of symmetry that would split it into two triangles.
Isosceles.
