Front

What does it mean for two triangles to be similar?

Back

Two triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in y over change in x).

If triangle XYZ is similar to triangle ABC, what can be said about their slopes?

Back

The slopes of corresponding sides of similar triangles are equal.

What is the definition of a function in mathematics?

Back

A function is a relation that assigns exactly one output for each input. In other words, for every x-value, there is one and only one y-value.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate grid, written in the form (x, y).

Front

How do you determine if a point lies on a function?

Back

To determine if a point (x, y) lies on a function, substitute the x-value into the function's equation and see if the resulting y-value matches the y-value of the point.

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.
