  • Name all these angles!
    Right, Straight, Acute, Obtuse
  • Define texture!
    Texture is a characteristic of surface! It produces different visual and tactile sensations.
  • What connects two points via the shortest path and continues indefinitely in both directions?
    Line
  • Which two circumferences have one common point on the line that joins their centers?
    Exterior Tangent Circumferences and Interior Tangent Circumferences
  • What is the space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet?
    Angle
  • Which of these angle relationships is complementary and which is supplementary? What do each add up to?
    Left is complementary and right is supplementary. 90 and 180 degrees, respectively.
  • Define secant, tangent and external lines! You can draw them if it helps.
    A secant line intersects the circumference at two points, a tangent line intersects the circumference at one point, and an external line never intersects
  • Which circumferences have no common points?
    Exterior Circumferences
  • What is the name of the red line shown? What does it do to the black line?
    Perpendicular Bisector
  • Draw a vertical, horizontal and oblique line!
    Variable
  • What parts are a, b, and V of this angle?
    a and b are sides and V is the vertex
  • Draw Concentric Circumferences!
    Variable
  • You have 60 seconds for everyone in your group to draw a different texture! Nobody can repeat!
    Variable
  • Explain the difference between a circle and a circumference!
    A circle is the surface contained WITHIN a circumference. OR A circumference is the perimeter of a circle or elipse.
  • Draw intersecting circumferences!
    Variable
  • What is part of a line between 2 points?
    Line Segment
  • Which of these angle relationships is adjacent and which is consecutive? Which shares a vertex?
    Left is consecutive, right is adjacent. Both share the vertex!
  • What are A, B, and C examples of?
    Point
  • What is the difference between natural and artificial textures?
    Natural textures are found in nature whereas artificial textures are manmade.
  • Label at least 5 parts of this circle! (NOT Circumference)
    Semicircle, diameter, circular segment, radius, circular sector
  • Draw Interior Circumferences!
    Variable
  • What is C an example of?
    Angle Bisector
  • Fill in all the parts of a circumference (7) on the board!
    Arc, centre, chord, diameter, circumference, radius, semi-circumference
  • What is an example of a NATURAL texture?
    Tree bark, leaves, hair, etc.
  • What is the difference between these two sets of lines?
    The one set is perpendicular, the other is parallel.
