What is AA Similarity in triangles?

Back

AA Similarity states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What is SAS Similarity in triangles?

Back

SAS Similarity states that if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, then the triangles are similar.

Front

What is SSS Similarity in triangles?

Back

SSS Similarity states that if the three sides of one triangle are proportional to the three sides of another triangle, then the triangles are similar.

Front

What is the definition of independent events in probability?

Back

Independent events are two or more events where the occurrence of one event does not affect the occurrence of the other.

Front

What is the definition of dependent events in probability?

Back

Dependent events are two or more events where the occurrence of one event affects the occurrence of the other.

How do you find the axis of symmetry of a quadratic function?

Back

The axis of symmetry of a quadratic function in the form f(x) = ax^2 + bx + c is given by the formula x = -b/(2a).

Front

What is the average rate of change of a function?

Back

The average rate of change of a function over an interval [a, b] is calculated as (f(b) - f(a)) / (b - a).

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula A = 1/2 * base * height.

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides: a^2 + b^2 = c^2.

Front

What is a linear function?

Back

A linear function is a function that can be graphically represented as a straight line, typically in the form f(x) = mx + b, where m is the slope and b is the y-intercept.
