It is not possible for a triangle to have more than one vertex with internal angle greater than or equal to 90°, or it would no longer be a triangle.The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate...The sum of the lengths of any two sides of a triangle is always larger than the length of the third sidePythagorean theorem: The Pythagorean theorem is a theorem specific to right triangles. For any right triangle, the square of the length of the hypotenuse equals the sum of the squares of the length...There are multiple different equations for calculating the area of a triangle, dependent on what information is known. Likely the most commonly known equation for calculating the area of a triangle involves its base, b, and height, h. The "base" refers to any side of the triangle where the height is represented by the length of the line segment dra...
Median The median of a triangle is defined as the length of a line segment that extends from a vertex of the triangle to the midpoint of the opposing side. A triangle can have three medians, all of which will intersect at the centroid (the arithmetic mean position of all the points in the triangle) of the triangle. Refer to the figure provided belo...
Jul 18, 2024 · Calculate the triangle side lengths if two of its angles are 60° each and one of the sides is 10 cm. The length of each side is 10 cm. Since two of the angles are 60° each, the third angle will be 180° - (60° + 60°) = 60°. As all the three angles are equal, the triangle is an equilateral triangle.

Jul 31, 2024 · All that you need are the lengths of the base and the height. In a right triangle, the base and the height are the two sides that form the right angle. Since multiplying these two values together would give the area of the corresponding rectangle, and the triangle is half of that, the formula is: area = ½ × base × height.
