Perry draws two planes, K and L, as shown. Which statement is true?
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.
imagine one piece of paper crossing through another what will their intersection look like?
idk im really confused on this subject
