"respectively" does not mean anything here.
A triangle is a polygon with three sides and three angles. It is one of the basic shapes in geometry and is often used in mathematical and scientific applications.
There are three types of triangles based on the length of their sides: equilateral, isosceles, and scalene. Triangles can also be classified based on the measure of their angles: acute, right, and obtuse.
The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. It can be written as a² + b² = c², where c is the length of the hypotenuse and a and b are the lengths of the other two sides.
The area of a triangle can be found by using the formula A = 1/2 * base * height, where A is the area, the base is the length of one side of the triangle, and the height is the perpendicular distance from the base to the opposite vertex.
In a triangle, the sum of all three angles is always 180 degrees. To solve for an unknown angle, you can subtract the known angles from 180 degrees. You can also use the properties of similar triangles or the law of sines and cosines to solve for unknown angles.
