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)
