Study Notes

Perpendicular Lines

  • Lines that intersect to create a right angle (90 degrees).
  • Example: In a geometric context, two perpendicular lines meet at a point forming a square corner or a right angle.

Intersecting Lines

  • Lines that cross each other but do not necessarily form a right angle.
  • Example: An X shape where the lines intersect without creating any 90-degree angles.

Right Angle

  • Formed when two lines create an angle that measures exactly 90 degrees.
  • Example: Found in squares and rectangles, where corners must be right angles for the shape to hold its properties.
