  • All Triangles=180 degrees

  • Right Triangle

    One angle is 90 (a right angle)

    Scalene

    No sides or angles are Equal

    Triangles

  • Isosceles

    2 sides and angles are Equal

    Equilateral

    All sides and angles are Equal

    Triangles

  • Acute AngleAn angle LESS than 90 degrees

  • An angle Greater than 90 degrees.Obtuse Angle

  • Right AngleAn angle that is EXACTLY 90 degrees

  • Two angles whose measures have a sum of 180 Supplementary Angles

  • Two angles whose measures have a sum of 90 Complimentary Angles

  • Two lines that intersect to form four right angles Perpendicular Lines

  • Intersecting LinesTwo lines that cross at one point

  • NEVER MEET

  • DiameterRadiusDiameter: A line segment that passes through the circle and has endpoints on the circleRadius: A line segment with one endpoint at the center of the circle and the other endpoint on the circle

  • Similar Figures: Figures with same shape, but NOT same size.Congruent Figures: Figures with the same size and shape

  • A line that divides a shape EXACTLY in half.Line of Symmetry

  • A polygon with four sides

  • A closed plane figure formed by three or more line segments. Polygon

  • A solid figure that has the shape of a round ball. All points are the same distance from the center

  • Perimeter: The distance around a figure (add up all the sides)

  • 23Numerator (TOP NUMBER)Denominator (BOTTOM NUMBER)

  • The smallest number, other than zero, that is a common multiple of two or more numbers Example: multiples of 6: 6, 12, 18, 24, 30, 36 multiples of 9: 9, 18, 27, 36, 45, 54 The LCM of 6 and 9 is 18

  • The greatest factor that two or more numbers have in common Example: 18: 1, 2, 3, 6, 9, 18 30: 1, 2, 3, 5, 6, 10, 15, 30 6 is the GCF of 18 and 30

  • Commutative Property The property that states that when the order of addends or factors is changed, the sum or product is the same Examples: 9 + 4 = 4 + 9 6 x 3 = 3 x 6 Associative Property The property that states that the way addends are grouped or factors are grouped does not change the sum or the product Examples: 12 + (5 + 9) = (12 + 5) + 9 (9 x 8) x 3 = 9 x (8 x 3)
