Understanding and applying these facts, theorems, and laws is critical to anyone who studies geometry. Exterior Angle: An exterior angle of a triangle is equal to the sum of the two opposite interior angles.Īrea Calculation: The area $$$A $$$ of a triangle with the side $$$b $$$ and the height $$$h $$$ dropped to this side can be found using the following formula: $$A=rac $$.Angle Sum: The sum of the interior angles of any triangle is always 180 degrees.What Are Some Key Facts, Theorems, and Laws Related to Triangles? Triangles are fundamental shapes in geometry and have various properties and theorems associated with them. Right-Angled Triangle: One of the angles is exactly 90 degrees, making it a right angle.Obtuse Triangle: One of the angles is greater than 90 degrees.Acute Triangle: All three angles are less than 90 degrees.Scalene Triangle: All sides have different lengths and all angles have different measures.Isosceles Triangle: It has two sides of equal length, and the angles opposite those sides are also equal.Equilateral Triangle: All three sides are of equal length, and all three angles are 60 degrees.Triangles can be categorized based on their sides and angles. These angles always sum up to 180 degrees, regardless of the triangle's shape or size. It is defined by its three straight sides and three internal angles. This will include the missing side lengths, angles, perimeter, and area.Ī triangle is a three-sided polygon. The calculator will instantly provide results based on your input.
