![]() ![]() We require two equal angles for any isosceles triangle. Any two angles of a triangle must have a sum of less than $180$ degrees. It is possible to calculate the missing angles of a triangle easily if you know what type it is. Similarly, if a 2 + b 2 < c 2, the triangle is obtuse.Hint: Triangle types are defined by angle and length properties. Given sides a, b, and c, where c is the longest side of an acute triangle: c 2 c 2, if side c is also the longest side, the triangle is an acute triangle.The points of concurrency (circumcenter, incenter, centroid, orthocenter) of an acute triangle all lie within the boundaries of the triangle.The interior angles of an acute triangle are all between 0° and 90°.Acute triangle propertiesīelow are some properties of acute triangles. In the scalene acute triangle above, none of the sides or angles are equal. The figure below shows a scalene acute triangle. Scalene acute triangleĪ scalene acute triangle is a triangle whose sides all have different lengths and whose angles are all less than 90°. Side c and angle C have different measures. For any acute isosceles triangle two sides and two angles are equal. An acute triangle has three angles that each measure less than 90 degrees. In the isosceles acute triangle above, sides a = b and angles A = B. Given that she drew a acute isosceles triangle. The figure below shows an isosceles acute triangle. Isosceles acute triangleĪn isosceles acute triangle is a triangle that has two sides of equal length and whose angles are all less than 90°. An isosceles triangle is a triangle which has two equal sides, and the angles opposite the equal sides are also equal. It may be acute, obtuse, equiangular, scalene, isosceles, or equilateral, but not a right triangle. ![]() An oblique triangle is any triangle that is not a right triangle. ![]() Note: All equiangular triangles are also equilateral. In the equilateral triangle above, sides a = b = c and angles A = B = C. An equiangular triangle has three congruent angles. The figure below shows an example of an equilateral triangle. All equilateral triangles are acute triangles because their interior angles will always be less than 90° by definition. Since the interior angles of a triangle sum to 180°, the interior angles of an equilateral triangle are all equal to 60°. Equilateral triangleĪn equilateral triangle is an acute triangle whose sides are all equal and whose interior angles all have the same measure. Types of trianglesĪn acute triangle can be categorized as an equilateral triangle, isosceles acute triangle, or a scalene acute triangle. An acute triangle can be equilateral, isosceles, or scalene. Since all of the interior angles are 60°, the acute triangle above is more specifically described as an equilateral triangle. An example of an acute triangle in real life is a yield sign: In an isosceles triangle, the lengths of two of the sides or, by one definition, at least. Acute triangle definitionĪn acute triangle is a 3-sided polygon in which the interior angles (the angles formed inside the triangle) all measure less than 90°. In an acute triangle, the measure of each angle is less than 90. ![]() Generally, triangles are categorized into 6 types: acute, obtuse, right, equilateral, isosceles, and scalene. What is an acute triangleĪn acute triangle is characterized by having no angles that measure larger than 90°. Home / geometry / triangle / acute triangle Acute triangleĪn acute triangle is a type of triangle in which the three internal angles have measures of less than 90°. ![]()
