Geometry terms
the same shape and same size
congruent
the point where the x-axis and y-axis intersect; represented by the points (0,0)
origin
What mathematical operation do you perform to find the difference?
Subtraction
Right angle
A number without a variable.
Constant
Rigid motion across a fixed line AB in a plane; like a mirror image; congruent
reflection
Each of the 4 sections of a coordinate plane made by the intersecting x- and y- axes.
quadrant
What mathematical operation do you perform to find the sum?
Addition
In a right triangle, the two sides next to the right triangle.
Legs
What mathematical operation do you perform to find the product?
multiplication
Rigid motion around a fixed center A; like a wheel; congruent
Rotation
The speed at which a variable changes over time; slope
Rate of change
A whole number or the negative of a whole numer
integer
A triangle that has a 90-degree angle
Right triangle
A combination of variables and numbers (like 6-x); no equal sign
Expression
Rigid motion by a constant distance in a single direction with no rotation or reflection; slide; congruent
translation
What is the slope intercept form for a linear equation?
y=mx+b
A constant that a variable or expression is multiplied by.
Coefficient
In a right triangle, the side opposite the right triangle.
hypotenuse
A mathematical sentence with an equals sign.
Equation
a transformation that changes the size of a geometric figure—enlarging or shrinking it—by a specific scale factor relative to a fixed point
Dilation
A point where a line or curve meets the y-axis.
y-intercept
Writing a nonzero number as 105
Scientific notation
If a right triangle has lengths a, b, and c where c is the length of the side opposite the right angle, then a2+b2=c2
The Pythagorean Theorem
A letter (like x) that we can use to mean different numbers at different times.
