Question

Perry draws two planes, K and L, as shown.
Which statement is true?

Answer 1

A. Plane K and plane L contain four lines because a theorem states that a line extends on both sides of a plane.

B. Plane K and plane L intersect along a line because a postulate states that if two planes intersect, then their intersection is a line.

C. Plane K and plane L intersect along two lines because a theorem states that there are only two planes that can pass through a line.

D. Plane K and plane L make a straight angle with each other because a postulate states that the measure of a straight angle is two right angles.

Answer 2

imagine one piece of paper crossing through another
what will their intersection look like?
