Module 9 Review Set

Front

What is the formula to find the midpoint of two points A(x1, y1, z1) and B(x2, y2, z2)?

Back

Midpoint M = ((x1 + x2)/2, (y1 + y2)/2, (z1 + z2)/2)

Front

Calculate the midpoint of A(6, -10, 7) and B(10, -12, -1).

Back

M(8, -11, 3)

Front

What is the Arithmetic Mean of two numbers a and b?

Back

Arithmetic Mean = (a + b) / 2

Front

Find the Arithmetic Mean between 6 and 20.

Back

13

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

If the lengths of the legs of a right triangle are 5 and 12, what is the length of the hypotenuse?

Back

Hypotenuse ≈ 13 (using Pythagorean theorem)
