This video explains how to find the area enclosed by a square and a quarter of a circle given the length of the diagonal of the square. It is first explained that the length of the side of the square is equal to the radius of the circle. Then the area to be calculated is equal to the area of the quarter of the circle subtracted from the area of the square.

In this video, we use the properties of symmetry and congruence of a regular hexagon to find its area given its perimeter. The hexagon can be decomposed into 6 equilateral triangles and therefore the area of one of these triangles is found and then multiplied by 6 to find the total area of the hexagon.

This video shows how to use trigonometric ratios and the Pythagorean theorem to solve three right triangle problems. In the first example, the hypotenuse and one angle are given. In the second example, the two sides that make the right angle are given and in the third example only the hypotenuse is given but the right triangle is an isosceles triangle.
