Question

1. a tangent constraint ensures:

a. a point lies on a line
b. two objects touch at exactly one point
c. circles share a center
d. two lines remain parallel

1. a symmetric constraint:

a. keeps two entities equal length
b. keeps features mirrored across a reference line
c. forces a feature to be vertical
d. locks a point at the center of a line

Explanation:

Para la pregunta 7, una restricción tangente significa que dos objetos tocan exactamente en un punto. Para la pregunta 8, una restricción simétrica mantiene las características reflejadas a través de una línea de referencia.
