Perry draws two planes, K and L, as shown.

Which statement is true?

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

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

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.

Plane K and plane L make a straight angle wi

option 4 isn't complete... what is it please?

anonymous · Answer

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.
