Question

determine if these shapes are similar, congruent, or neither.
similar neither congruent

Explanation:

Step1: Recall the definitions

Similar shapes have proportional corresponding sides. Congruent shapes have equal corresponding sides.

Step2: Check the side - length ratio

Let's assume the triangles are equilateral (since all sides are marked as equal in each triangle). The ratio of the sides of the red triangle to the orange triangle is $\frac{9}{8}$. Since $\frac{9}{8}
eq1$, they are not congruent. But if they are equilateral (all angles are $60^{\circ}$), by the Side - Side - Side (SSS) similarity criterion (for equilateral triangles, all sides are in proportion), they are similar.

Answer:

similar
