A triangle is said to be valid if the sum of the lengths of any two sides is always greater than the length of the third side.

The third angle of a triangle is the measure of the angle opposite the third side of the triangle.

The fourth angle of a quadrilateral is the measure of the angle opposite the angle that is adjacent to both angles of the quadrilateral.

The sum of the interior angles of a polygon is the total of all the angles inside the polygon.

The interior angle of a regular polygon is the angle between two adjacent sides of the polygon.

Area Of Triangle

The area of a triangle is the measure of the amount of space inside the triangle.

The area of a sector of a circle is the measure of the amount of space inside the sector, which is a portion of the circle enclosed by two radii and an arc.

The measure of space occupied by a cube, which is a three-dimensional geometric shape with six equal square faces that meet at right angles. The volume of a cube is calculated using the formula V = s…

The surface area of a cylinder is the total area of all its faces, including the top and bottom faces and the lateral surface.

The surface area of a cone is the total area of all its faces, including the base and lateral surface.

The surface area of a pyramid is the total area of all its faces, including the base and lateral surface.

The area of a circle given the center and a point on the circle is the measure of the amount of space inside the circle, given the center and one point on the circle.

The curved surface area of a cylinder is the area of the lateral surface of the cylinder, which does not include the top and bottom faces.

The conversion from degrees to radians is a way to express angles in terms of the ratio of the length of an arc of a circle to the radius of the circle.

The conversion from radians to degrees is a way to express angles in terms of degrees instead of radians.

Complementary angles are two angles whose sum is 90 degrees, while supplementary angles are two angles whose sum is 180 degrees.

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.

The equation of a line from two points is the formula for finding the equation of a straight line when given two points on the line.

Trigonometry is the branch of mathematics that deals with the relationships between the sides and angles of triangles.
