I don't think they can actually.
That is kind of a trick question.
A scalene triangle can have an obtuse angle and two different acute angles.
Yes, an obtuse triangle can have two congruent angles, where for the obtuse angle measuring A degrees, each of the two other angles measures (180-A)/2.
If you are classifying triangles by their angles, an obtuse triangle has one obtuse angle and two acute angles. A triangle can have at most one obtuse angle. If the two acute angles are congruent, the triangle would also be isosceles.
An obtuse triangle whose other two angles will be acute angles
Classification of triangles according to sides: -Scalene Triangle - a triangle with no 2 congruent sides. -Isosceles Triangle - a triangle with at least 2 congruent sides. -Equilateral Triangle - a triangle with 3 congruent sides. Classification of triangles according to angles: -acute triangle - a triangle with 3 acute angles. -right triangle - a triangle with one right angle. -equiangular triangle - a triangle with 3 congruent angles. -obtuse triangle - a triangle with one obtuse angle.
how you name a triangle by its angles is like acute, obtuse, or right triangle. you do that by seeing if the angle has a 90 degree angle in it then its a right angle, if all the angles are 90 degrees or less than its an acute triangle. and if the triangle has one angle that is over 90 degrees than it is an obtuse triangle. to name a triangle by its sides is if its equilateral, equiangular, or regular. if its equilateral then all the sides are congruent. if its equiangular then all the angles are congruent. if its regular, then all the sides and angles are congruent to each other (for example and octogon). :)
Equilateral triangle = All sides congruent Scalene triangle = No sides congruent Isosceles triangle = At LEAST two sides congruent Right triangle = Triangle with one right angle Obtuse triangle = Triangle with ONE obtuse angle Acute triangle = Triangle with ALL acute angles
An obtuse triangle has 1 obtuse angle and 2 acute angles
A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
No, an obtuse triangles has one obtuse angle and two acute angles. If a triangle has an obtuse angle, it is considered obtuse and cannot be acute.
It is a scalene triangle
