What is the hypotenuse?

The side of a right triangle which is opposite to the right angle.


100

What are complementary angles?

Two angles whose measures add up to 90 degrees

100

What is the diameter?

This line segment spans exactly across the circle, passing directly through the center.

100

What is an equilateral triangle

A triangle with three equal sides

100

What is an outlier?

A data point that falls far away from all the other points in the dataset

200

What is the tangent?

The ratio of the opposite leg to the adjacent

200

What are supplementary angles?

Two angles whose measures add up to 180 degrees 

200

What is the radius?

This straight line segment starts at the very center of the circle and touches the outer edge.

200

What is an isosceles triangle?

A triangle with at least two equal sides.

200

What is a cluster?

A section on a scatter plot where data points are tightly grouped together.

300

What is cosine?

The ratio of the adjacent leg to the hypotenuse.

300

What are vertical angles?

Two angles opposite each other at the intersection of two lines. They are always equal

300

What is a chord?

Any line segment that goes from one side of a circle to another but does not pass through the center

300

 What is a scalene triangle?  

A triangle with no equal sides

300

What is a gap

An empty space or interval in a dataset where no data points appear.

Right angled Triangle.

400

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.

400

What is Pi ? 

The name for a circles circumference to its diameter

400

What is the sum of all interior angles in any triangle?

180 degrees

400

What is a positive correlation (or association)?

A relationship where one variable increases as the other variable also increases.

500

In a right triangle where (sin40^\circ) = x\), what is the equivalent function expression?

cos(50degrees)=x

500

What are corresponding angles?

When parallel lines are cut by a transversal, these angles are in the same relative position at each intersection.
