What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

What is the circumcenter of a triangle?

Back

The circumcenter is the point where the perpendicular bisectors of a triangle's sides intersect, and it is equidistant from each vertex of the triangle.

Front

What is a sample survey?

Back

A sample survey is a research method where a subset of individuals is selected from a larger population to gather data and make inferences about the whole population.

Front

What does it mean for a graph to represent a function?

Back

A graph represents a function if for every input (x-value), there is exactly one output (y-value).

Front

What is the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width.

Front

What is the incenter of a triangle?

Back

The incenter is the point where the angle bisectors of a triangle intersect, and it is equidistant from each side of the triangle.

Front

How do you find the length of a rectangle if the area and width are known?

Back

To find the length, divide the area by the width: Length = Area / Width.

Front

What is the cosine function?

Back

The cosine function, denoted as cos(x), is a trigonometric function that relates the angle x to the ratio of the adjacent side to the hypotenuse in a right triangle.

Front

What is the difference between a census and a sample survey?

Back

A census collects data from every member of a population, while a sample survey collects data from a subset of the population.

Front

What is the significance of the angle bisector in a triangle?

Back

The angle bisector of a triangle divides the angle into two equal parts and intersects the opposite side at a point that is proportional to the lengths of the other two sides.
