Below are sample questions representative of the exercises included on this worksheet and related GEO.69 Identify points, lines, planes, and intersections in diagrams skill assessments:

Problem 1Difficulty: Mastery
Use the diagram. A shaded plane is labeled Y. Points L, M, and N are collinear in the plane, while point O is in the plane but not on line LN. Which choice gives a valid plane name and explains why?
Aplane LMN, because any three labeled points name a plane
Bplane LMO, because L, M, and O are noncollinear
Cline LNO, because O is off the line
Dpoint Y, because the plane label is a point
Solution & Explanation:A plane needs three noncollinear points when named by points. L, M, and N are collinear, but L, M, and O are not, so plane LMO is valid.
Problem 2Difficulty: Mastery
Use the 3D diagram. Planes P and Q intersect in line t. Line r lies in plane P, line s lies in plane Q, and r and s meet at point M on line t. What is common to line r, line s, plane P, and plane Q?
Apoint M
Bline t
Cplane P
Dno intersection
Solution & Explanation:The two planes share line t, and the two lines r and s meet at M on that shared line. The only object common to all four is point M.
Problem 3Difficulty: Mastery
Use the diagram. Two distinct planes are being compared. Which situation cannot occur for two distinct planes?
AThey do not intersect.
BThey intersect in exactly one line.
CThey share exactly two intersecting lines.
DThey share a line containing many points.
Solution & Explanation:If two planes share two intersecting lines, those lines determine one plane, so the planes would be the same plane. Distinct planes cannot share exactly two intersecting lines.
