Skills in this topic, easy to hard

  1. Prisms, pyramids and the faces of solidsTwo bases: a prism; one base and a point: a pyramid. Named after the base
  2. Line segments and quadrilaterals4 points: 3 + 2 + 1 = 6 segments
  3. Angles and comparing themHow far it opens, not how long its sides are
  4. Right, acute and obtuse anglesSmaller than a right angle: acute; bigger: obtuse
  5. Right angles and perpendicular linesThe perpendicular segment is the shortest
  6. Horizontal and vertical lines, and raysCount end points: 0 a line, 1 a ray, 2 a segment
  7. Squares and rectanglesRectangle: opposite sides equal; square: all four
