A full rotation only

The angle at a triangle vertex

Any angle between two lines

Question Nr. 2 out of 10

What is a dihedral angle?

Any angle between two lines

The angle between two half-planes with a common edge

A full rotation only

The angle at a triangle vertex

Question Nr. 3 out of 10

Which statement is a criterion for a line parallel to a plane?

Every line is parallel to every plane

A line parallel to a line in the plane and not lying in the plane is parallel to the plane

A line in the plane is outside it

One common point proves parallelism

Question Nr. 4 out of 10

How is the angle between an oblique line and a plane found?

Ignore the projection

Treat every oblique as perpendicular

Use the perpendicular projection of the oblique segment onto the plane

Measure any plane angle

What relative positions can a line and a plane have?

It can only be perpendicular

It always has two intersections

It always lies in the plane

It may lie in the plane, intersect it once, or be parallel to it
