If a triangle has one acute angle is the triangle necessarily acute?
No, an acute triangle must have all 3 angles under 90 degrees. A triangle can have an acute angle and still be a right triangle or an obtuse triangle.
Can an acute triangle have all acute angles?
An acute triangle *is* a triangle with all acute angles. For example, an equilateral triangle where all three angles are 60°.If a triangle has one 90° angle, then it is a right triangle.If it has one angle greater than 90°, then it is an obtuse triangle.
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.
If a triangle has one acute angle is the triangle acute?
yes, it only needs one acute angle out of the three to make it an acute triangle.
Is a triangle a Acute Angle Obtuse Angle Right Angle?
A triangle is not an angle. A triangle is made of three angles. -- All three of them can be acute, but they don't need to be. -- One of them can be obtuse but doesn't need to be. -- One of them can be a right angle but doesn't need to be. -- If any angle in the triangle is right or obtuse, then the other two need to be acute.

An acute triangle *is* a triangle with all acute angles. For example, an equilateral triangle where all three angles are 60°.If a triangle has one 90° angle, then it is a right triangle.If it has one angle greater than 90°, then it is an obtuse triangle.
What is the difference between a right an acute and obtuse triangle?
A right triangle has one angle a right angle (90o) An obtuse triangle has one angle an obtuse angle (> 90o) An acute triangle has all angles acute (< 90o)
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.
What is the definition for an acute triangle?
An acute triangle is a triangle with all angles acute (for example, a triangle with angles 64 ,36, and 80). An acute angle is an angle less than 90 degrees. Also, all angles in a triangle MUST sum to 180 degrees.
Do all angles in a triangle have to be acute?
No, a triangle can have a right angle or an obtuse angle as well.
Is a right triangle acute true or false?
False ------------------------------------ An acute triangle is one in which all angles are acute angles. An acute angle is less than 90°. A right angle is 90°, which is equal to 90° not less than 90° Therefore all the angles of a right triangle are not all acute Thus a right triangle is not an acute triangle.
If a triangle has one acute angle is the triangle acute?
yes, it only needs one acute angle out of the three to make it an acute triangle.
Are all equallateral triangles acute?
-- An 'acute triangle' is a triangle in which each of the three interior angles is an acute angle. -- Each of the three interior angles in every equilateral triangle is a 60-degree angle. -- Any angle of less than 90 degrees is an acute angle. -- It sure looks like every equilateral triangle does fit the definition of 'acute triangle'.
How do you classify a triangle by its angles?
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
If one angle in a triangle is acute can the other two angle also be acute?
Yes. In this case a triangle is called an acute triangle.
Is a triangle a Acute Angle Obtuse Angle Right Angle?
A triangle is not an angle. A triangle is made of three angles. -- All three of them can be acute, but they don't need to be. -- One of them can be obtuse but doesn't need to be. -- One of them can be a right angle but doesn't need to be. -- If any angle in the triangle is right or obtuse, then the other two need to be acute.
