Geometry Recap

What are parallel lines?

• Lines that intersect

• Lines that exist and don't run into each other

• Lines that are a set distance from each other and never intersect

• Lines that are lol

What are perpendicular lines?

• Lines that intersect

• Lines that intersect and make V's

• Lines that intersect and make acute and obtuse angles

• Lines that intersect and create right angles

What is a right angle?

• An angle that points to the right

• An angle that opens to the right

• An angle that is always on the right side

• An angle that measures 90 degrees

What is an acute angle?

• An angle that measures more than 90 degrees

• An angle that measures less than 90 degrees

• An angle that measures 90 degrees

• An angle that is cute

What is an obtuse angle?

• An angle that measures more than 90 degrees but less than 180 degrees

• An angle that measures less than 90 degrees

• An angle that measures 90 degrees

• An angle that is becoming obtuse

What is a straight angle?

• An angle that points in the straight direction

• An angle that starts and finishes

• An angle that's more than 90 degrees but less than 360 degrees

• An angle that measures exactly 180 degrees
