… Less than 90° – all three angles are acute and so the triangle is acute. Can a acute triangle be a right triangle?Ī triangle where all three internal angles are acute (less than 90 degrees). … Hence having two angle obtuse, construction of a triangle is not at all possible. So adding that two angles only we will get 180∘ or more than that. Obtuse angle is an angle which has magnitude more than 90∘. We have the property that the sum of the angles of a triangle is always 180∘. Triangle with sides in option (A) can’t be drawn.Īdvertisements Can a triangle have two obtuse angles? If the larger side is equal to or greater than the sum of other two sides, the triangle can’t be drawn. Since a triangle is obtuse or right if and only if one of its angles is obtuse or right, respectively, an isosceles triangle is obtuse, right or acute if and only if its apex angle is respectively obtuse, right or acute. Can an isosceles triangle be an obtuse triangle? All of each may be of different or the same sizes any two sides or angles may be of the same size there may be one distinctive angle. Triangles can be classified either according to their sides or according to their angles. It will always have angles of 60° in each corner. An equilateral triangle has three equal sides and angles. What do you call a triangle with 3 equal sides?Įquilateral. The red triangle is an obtuse, scalene triangle. Triangles can be classified by both their angle measures and their sides. One angle has a measure greater than a right angle. Which of the following triangles is an obtuse scalene triangle?Īn obtuse triangle has one obtuse angle. Look at an acute scalene triangle given below whose angles are 65°, 35°, and 80°. In geometry, an acute scalene triangle can be defined as a triangle whose angles are less than 90 degrees and all three sides and angles are different in measurement. What angles make an acute scalene triangle? … Obviously no equilateral triangle can be a right-angled triangle, since you can’t have three right angles in a triangle, at least not in Euclidean geometry. Nearly every triangle is a scalene triangle. Is every right triangle a scalene triangle? … A scalene triangle is one which have all three sides of a triangle of different lengths and all three angles of different measures. What is the difference between a scalene and obtuse triangle?Īn obtuse triangle is any triangle that has an obtuse angle. Some right triangles can be a scalene triangle when the other two angles or the legs are not congruent. Also the angles of a scalene triangle have different measures. Which figure is a scalene triangle?Ī scalene triangle is a triangle in which all three sides have different lengths. That means that isosceles triangles never can be scalene. Scalene triangles cannot have equal sides, nor equal angles. Can a scalene triangle be isosceles?Įxplanation: Isosceles triangles has two equal sides, and two equal angles. (In other words, each angle of an acute triangle is less than 90 degrees.) A SCALENE triangle is one in which all sides have different lengths (and therefore, all angles have different measures). What is the difference between a scalene and acute triangle?Īn ACUTE triangle contains three acute angles. Does a scalene triangle always have an acute angle?Ī scalene triangle can have either 2 or 3 acute angles. A scalene triangle can be acute-angled or obtuse-angled or right-angled.
