What is the formula to calculate the midpoint between two points (x1, y1) and (x2, y2)?

Back

The midpoint M is given by M = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is a scalene triangle?

Back

A scalene triangle is a triangle in which all three sides have different lengths.

Front

What does the ASA (Angle-Side-Angle) theorem state about triangles?

Back

If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the definition of similar triangles?

Back

Similar triangles are triangles that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are proportional.

Front

How do you find the area of a triangle given its base and height?

Back

The area A of a triangle is given by A = (base * height) / 2.

Front

What is the SSS (Side-Side-Side) theorem?

Back

The SSS theorem states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the formula for the Pythagorean theorem?

Front

What is the definition of an isosceles triangle?

Back

An isosceles triangle is a triangle that has at least two sides of equal length.

Front

What is the relationship between the angles and sides of similar triangles?

Back

In similar triangles, corresponding angles are equal, and corresponding sides are proportional.
