acute scalene triangle: all sides have different lengths.Īs you see, once we understand what an acute triangle is, it's obvious how to decide if a triangle is acute if you know its angles: just take a look at these angles and make sure they are all strictly less than 90° (π/2 rad).acute isosceles triangle: two sides are equal and acute equilateral triangle: all three sides are equal acute isosceles triangle: two sides are equal and acute scalene triangle: all sides have different lengths.acute equilateral triangle: all three sides are equal.A right-angled triangle will have one angle that is 90°, which means the. In an equilateral triangle, all angles will be 60°. Obtuse triangle: has an obtuse angle (and two acute angles).Īcute triangles can be further divided into three categories, based on the side lengths (more precisely, on side length ratio): An isosceles triangle will have two angles the same size.When none of the sides of a triangle have equal lengths, it is referred to as scalene, as depicted below. Right triangle: has a right angle (and two acute angles) and For example, a triangle in which all three sides have equal lengths is called an equilateral triangle while a triangle in which two sides have equal lengths is called isosceles.Acute triangle: all three of its angles are acute.Scalene Triangle: A triangle where all sides are of different length. Isosceles Triangle: A triangle with at least two sides of equal length is Isosceles triangle. Obtuse angle: it measures more than 90˚ and less than 180˚.īased on that, we distinguish three types of triangles: Equilateral Triangle: When all side lengths of a triangle, are equal.Right angle: it measures exactly 90˚ and.Acute angle: it measures less than 90˚.Recall there are three types of angles that you can encounter while dealing with triangles:
