  • What is the difference between a ray, a line and a line segment?
    A line segment has two endpoints, a ray has only one end point and a line has no end points.
  • What is the difference between parallel, perpendicular and intersecting lines?
    Parallel lines never intersect. Perpendicular lines form four 90° angles and intersecting lines form angles that are not 90°
  • What is the name of the tool you use to measure angles?
    Protractor
  • How many dimensions does a solid have?
    It has three
  • What is a line?
    A line is an object that extends without end in both directions. It is usually drawn with arrowheads to show that it goes on forever.
  • Mention four instruments you need for Geometry
    Protractor, set square 60 degree, set square 45 degrees, ruler, compass
  • How many dimensions does a point have?
    Zero
  • What is a line segment?
    A line segment is a part of a line with two end points.
  • When two or more lines cross each other in a plane, they are called __________ .
    Intersecting lines.
  • What do points help us do?
    They help us describe specific locations in space.
  • The lines that intersect to form four right angles are called _________
    Perpendicular lines
  • WHen two rays share an end point, an ___________ is formed.
    angle
  • What is a plane?
    A plane is a flat surface with two dimensions: length and width
  • The lines that never meet are called ______________
    Parallel lines
  • What is a point?
    A point is an object that has no length or width.
  • How many demensions does a line have?
    It has only one dimension, length
  • What are parallel lines?
    Parallel lines are lines that never intersect. They never meet.
  • What is the name of the point shared by intersecting lines?
    Point of intersection
  • What is geometry?
    Geometry is a branch of mathematics that studies the sizes, shapes, positions angles and dimensions of things.

  • What is a ray?
    A ray is half of a line, with one end point.
  • What is the name of the tool you use to trace circles?
