Unit 1: Constructions and Rigid Transformations
A specific place on a graph; usually marked with a dot
Point
Same shape and same size
Congruent
The amount of space inside a 2D figure
Area
Rise/ Run; change in y/ change in x; the steepness of a line
Slope
What two colors combine to create orange?
Red and yellow
Two lines that will never cross
Parallel
Same shape but different size
Similar
The amount of space inside a 3D figure
Volume
The distance from the center of a circle to any point the circle; Twice the diameter; All circles only have 1 of these
Radius
The 5 vital organs of the human body are the: brain, lungs, heart, liver and __________
Kidneys
Two lines that make right angles when they cross
Perpendicular
If 3 sides are congruent on each triangle, then triangles are congruent.
Side-Side-Side triangle congruence theorem (SSS)
The longest ride on a right triangle; The side opposite the right angle
Hypotenuse
A formula for the square root of: (x2 - x1)2 + (y2 - y1)2
Distance formula
What is the most populated city in the world?
Tokyo, Japan
Transformations that do not change size; Reflections, Rotations and Translations
Rigid transformations
A transformation that produces an image that is the same shape, but different size; Creates similar figures; Not a rigid transformation
Dilation
Theta
The name for a graph of a quadratic function
Parabola
What quarterback has won the most superbowls in the NFL?
Tom Brady
A line through the vertex of an angle that divides it into TWO equal angles
The ratio of dilation; how much bigger or how much smaller; If between 0 and 1, the figure will get smaller; If bigger than 1, the figure will get bigger
Scale Factor
Trig ratio where opposite side/ hypotenuse
Sine
(x - h)2 + (y - k)2 = r2 is the equation for what shape?
Circle
What is the closest planet to the sun?
Mercury
