Do all triangles have an acute angle?
All triangles have at least 2 acute angles. All 3 angles of a triangle will equal 180 degrees.
Can an triangle have exactly one acute angle?
No because a triangle must have at least 2 acute angles along with a 3rd angle in which all 3 angles must add up to 180 degrees.
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
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)
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.
What is a triangle with all acute angle?
An acute triangle.
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.

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.
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'.
