Does obtuse triangle have to be scalene?
An obtuse-angled triangle can be a scalene triangle or isosceles triangle but will never be equilateral since an equilateral triangle has equal sides and angles where each angle measures 60°.
Is it possible to have a regular triangle that is obtuse?
No, a triangle cannot have an obtuse and a right angle.
What triangle can be obtuse?
An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Since a triangle’s angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.
Can an obtuse triangle be equilateral triangle?
An obtuse triangle cannot be an equilateral triangle. All triangles have three sides, and three angles. The angles must add up to 180 degrees.
What is the difference between a scalene and obtuse triangle?
An obtuse triangle is any triangle that has an obtuse angle. A scalene triangle is one which have all three sides of a triangle of different lengths and all three angles of different measures.
What does a scalene triangle look like?
Scalene triangles have three unequal angles. The shortest side is opposite to the smallest angle, The medium side is opposite to the medium angle, The longest side is opposite the largest angle.
Why can’t a triangle be obtuse and right?
A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. The side opposite the obtuse angle in the triangle is the longest.
Why is it impossible to draw an obtuse equilateral triangle?
Explanation: The angles in an equilateral triangle are all 60 degrees. since all three angles are equal divide the total degrees in an triangle by 180 by 3. 60< 90 so an equilateral triangle can not have an obtuse angle.
What does a obtuse triangle look like?
An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°. Here, the triangle ABC is an obtuse triangle, as ∠A measures more than 90 degrees.
What is a scalene obtuse triangle look like?
An obtuse triangle is any triangle that has an obtuse angle. An obtuse angle is one that measures greater than 90 degrees. A scalene triangle is one which have all three sides of a triangle of different lengths and all three angles of different measures.
