trignometry
What is the hypotenuse?
The side of a right triangle which is opposite to the right angle.
What are complementary angles?
Two angles whose measures add up to 90 degrees
What is the diameter?
This line segment spans exactly across the circle, passing directly through the center.
What is an equilateral triangle
A triangle with three equal sides
What is an outlier?
A data point that falls far away from all the other points in the dataset
What is the tangent?
The ratio of the opposite leg to the adjacent
What are supplementary angles?
Two angles whose measures add up to 180 degrees
What is the radius?
This straight line segment starts at the very center of the circle and touches the outer edge.
What is an isosceles triangle?
A triangle with at least two equal sides.
What is a cluster?
A section on a scatter plot where data points are tightly grouped together.
What is cosine?
The ratio of the adjacent leg to the hypotenuse.
What are vertical angles?
Two angles opposite each other at the intersection of two lines. They are always equal
What is a chord?
Any line segment that goes from one side of a circle to another but does not pass through the center
What is a scalene triangle?
A triangle with no equal sides
What is a gap
An empty space or interval in a dataset where no data points appear.
What is the only type of triangle that basic trigonometric functions can be applied to?
Right angled Triangle.
Two angles opposite each other at the intersection of two lines. They are always equal
Two angles that share a common vertex and side, but do not overlap.
What is Pi ?
The name for a circles circumference to its diameter
What is the sum of all interior angles in any triangle?
180 degrees
What is a positive correlation (or association)?
A relationship where one variable increases as the other variable also increases.
In a right triangle where (sin40^\circ) = x\), what is the equivalent function expression?
cos(50degrees)=x
What are corresponding angles?
When parallel lines are cut by a transversal, these angles are in the same relative position at each intersection.
What is the formula used to calculate the distance around the outside of a circle
C=(pi)d or C=(pi)2r
What is the measurement of every angle in an equilateral triangle.
60 degrees
What is no correlation?
A relationship showing no relationship or pattern whatsoever between the two variables
