Question

determine whether the hypothesis of each given conditional is true from the given information.
given: if a, b, c, and d are collinear, then they lie in the same plane.
a, b, c, and d lie in the same plane.
conclusion: a, b, c, and d are collinear.
given: if (overrightarrow{bd}) bisects (angle abc), then d lies in the interior of (angle abc).
d lies in the interior of (angle abc).
conclusion: (overrightarrow{bd}) bisects (angle abc).

Explanation:

Step1: Analyze first conditional

Just because points lie in same - plane doesn't mean they are collinear.

Step2: Analyze second conditional

Just because a point is in interior of an angle doesn't mean a ray from it bisects the angle.

Answer:

No, No
