Tricky geometry stuff?

Question

Always, Sometimes or never?
<--> TQ and <--> QT are _______the same line
-->JK and -->JL are ___ the same ray?
Two lines in the same plane are____parallel
Two lines that lie in parallel planes are _____parallel

1st one gets 10 pts if right

Answer 1

1) <--> TQ and <--> QT are _______the same line.
Always

2) -->JK and -->JL are ___ the same ray?
sometimes ( if K and L belong to ray then the answer will be always)
3) Two lines in the same plane are____parallel.
sometimes

4)Two lines that lie in parallel planes are _____parallel
sometimes

Answer 2

Since two points determine a line, and you have lines
TQ and QT having the same points, they are always the same lines.

Rays JK and JL each have a common end point, so sometimes, provided k and l are points in the same ray then they would be the same ray, but try drawing other rays which would not be the same.

Think of a plane as a flat surface, can you draw lines that are not parallel in that plane? Can you draw lines that are parallel?

Think of two parallel planes, like a 1st and 2nd floor of a building, can you draw lines that are not parallel? Can you draw lines that are parallel.

The word is sometimes for the last two cases.

No this is not tricky.

Answer 3

TQ and QT are always the same line
JK and JL are never the same ray
Two lines in the same plane are sometimes parallel
Two lines in parallel planes are never parallel. They are called skew lines.

Answer 4

frequently speaking, many that excell in Algebra I or Algebra II do not truthful nicely in Geometry. The convese additionally seems to be like actual. I made C's interior the Algebra's, yet a ninety 8 avg in Geometry. Geometry is extra seen and spacial. stable good fortune!!
