What triangle is never an acute or obtuse triangle?
right triangle
Isosceles triangles may be obtuse or acute but never right?
false
Can a right triangle be acute or scalene or isosceles?
A right triangle may be isosceles or scalene (though not at the same time), but never acute, since an acute triangle is defined as having all interior angles less than 90°. A right triangle by definition has one 90° angle.
Is a scalene always isosceles?
No. A scalene triangle is never isosceles. An isosceles triangle has two equal sides. A scalene triangle has none.
Can a isosceles triangle can be scalene.?
An isosceles triangle can never be a scalene triangle but it can take the shape of a right angle triangle
What triangle is never acute of obtuse?
No triangle is never acute in the sense that every triangle has at least two acute angles.
What triangle is never an acute or obtuse triangle?
right triangle
Isosceles triangles may be obtuse or acute but never right?
false
Is it true that isosceles triangles may be obtuse or acute but never right?
No, it is not true.
Is a triangle three obtuse angles?
No not never can a triangle have 3 obtuse angles but it can have 3 acute angles
Can an Isosceles triangles may be obtuse or acute but never right?
Not true. A triangle with angles of 90, 45 and 45 is a right angled isosceles triangle. If you take a square piece of paper and fold it in half - from corner to corner - you will get this shape.
Can an acute and obtuse triangle be similar?
No. Similar triangles have all the same angles. An acute triangle can never have an obtuse angle, so the two cannot be similar.
Can a right triangle be both a scalene and isosceles?
Sometimes an isosceles triangle but never a scalene triangle with 3 interior acute angles.
Can a right triangle be acute or scalene or isosceles?
A right triangle may be isosceles or scalene (though not at the same time), but never acute, since an acute triangle is defined as having all interior angles less than 90°. A right triangle by definition has one 90° angle.
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 a triangle sometimes always or never have a right triangle and an obtuse triangle?
A triangle can never include a right angle and an obtuse angle together in it.
Is a scalene always isosceles?
No. A scalene triangle is never isosceles. An isosceles triangle has two equal sides. A scalene triangle has none.
