Question

Using vector method prove that the medians of a triangle are concurrent

Answer 1

The diagonal of the rectangle is the hypotenuse of these triangles. We can use Pythagoras' Theorem to find the length of the diagonal if we know the width and height of the rectangle.

As a formula:

Diagonal = √ w 2 + h 2

where:

w is the width of the rectangle

h is the height

Use the calculator on the right to calculate the properties of a rectangle.

Enter the two side lengths and the rest will be calculated. For example, enter the two side lengths. The area, perimeter and diagonal lengths will be found.
