Are an obtuse triangle and a acute triangle sometimes congruent?

Congruent means "equals" or "the same." Basically if you take a shape and flip it over or mirror it, or do anything else that copies the original in size and shape, it is congruent to the original.
An obtuse triangle has one angle greater than 90* and an acute triangle has three angles that are less than 90*. No matter how you turn or flip or mirror those triangles, acute will never be obtuse and obtuse will never be acute. But if you take an acute triangle, and flip it upside down, it is still acute, and still has the same proportions, and therefore is congruent to the original.

Does obtuse triangle have any angles congruent?
An obtuse triangle must have two acute angles and these can be congruent.
What triangle has an obtuse angle and no congruent sides?
A scalene triangle can have an obtuse angle and two different acute angles.
What do the triangles look like and what are the names?
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
Can an obtuse triangle have congruent sides?
Yes if it is in the form of an isosceles triangle with the other 2 acute angles being equal
Does a obtuse angled isosceles triangle have congruent side?
All isosceles triangles must have two congruent sides otherwise it is not isosceles. Whether it is acute angled, right angled or obtuse angled is irrelevant.
Does obtuse triangle have any angles congruent?
An obtuse triangle must have two acute angles and these can be congruent.
What triangle has an obtuse angle and no congruent sides?

What is triangle is an obtuse triangle?
An obtuse triangle is a type of triangle that has no congruent sides. Basically none of its sides are the same size.
Which triangle has two acute angles and one obtuse angle?
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.
What figure shows a triangle with no sides congruent and 1 obtuse angle?
An obtuse triangle whose other two angles will be acute angles
Classification of triangle?
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.
Can an obtuse triangle have congruent sides?
Yes if it is in the form of an isosceles triangle with the other 2 acute angles being equal
What is the difference between an acute triangle and an obtuse triangle?
An acute triangle has three interior acute angles An obtuse triangle has one obtuse and two acute interior angles
Does an acute triangle have obtuse 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.
What are the names of the triangles and how can you tell?
right triangle forms a 90 degree angle scalene triangle has no congruent sides isosceles triangle has at least 2 congruent sides equilateral triangle has 3 congruent sides acute triangle all angles measure less than 90 degrees and the obtuse triangle contains 1 obtuse angles.
How can you determine if a triangle is acute obtuse or right triangle?
If all of the angles in a triangle are acute then it is an acute triangle. If one angle is right (or 90 degrees) then it is a right triangle. If one angle is obtuse then it is an obtuse triangle.
