Shapes
Moving a shape so that it is in a different position, but still has the same size, area, angles and line lengths
What is transformation?
A transformation created proportionally by enlarging or reducing a figure
What is dilation?
How you find slope
rise over run
or
y - y over x - x
93 * 95
98
Write in scientific notation:
0.0000001045
1.045 * 10^-7
If a shape is dilated, does its size change?
Yes
Having the same size and shape
What is congruent?
A function (equation) whose graph is a straight line and a constant slope
What is linear function?
A method of writing very large (34,200,000) or very small (0.0000029) numbers using powers of 10
What is scientific notation?
Solve.
7 (2x - 4) = 42
x=5
A transformation made by turning or spinning a figure around a given point
What is rotation?
What is the same in two similar shapes?
The angles
The slope intercept form of writing the equation of a straight line.
What is y = mx + b
5^7/5^9
1/5^2
What is the slope of these two points?
(2, 1500)
(4, 1200)
slope = -150
A transformation created by flipping an image over a line
What is reflection?
Length x width x height of a rectangular prism.
What is volume?
What is it called when an input-output relationship that has exactly one output (y-value) for each input (x-value)
What is a function?
How many solutions do 2 parallel lines have?
None
Solve the system of equations:
2x+ 3y = 11
4x - 2y = -2
(1,3)
Transformation created by sliding an object
What is translation?
Opposite the right angle - it is also the longest side of a right triangle
What is the definition of hypotenuse?
When we graph a system of equations, this is the solution.
What is point of intersection?
In a triangle, there are two equal angles and another angle that is 3.5 times the measure of one of those angles. How big are the smallest angles in the triangle?
20 degrees
