What triangle has 3 acute angles and 3 equal sides?
Any triangle that has three equals sides must have three acute angles and is equilateral.
Does an isosceles triangle have to have three acute angles?
No. The angle that isn't acute must be the unique angle, though.
What is the least amount of angles and acute triangle can have?
If you meen the three angles, all tirangles angles add to 180 degrees. But all of the angles must be different, that's what makes it an acute triange. So three.
Can a triangle have one acute angles?
nope. if it did, the two other ends wouldn't be able to meet with obtuse angles. A triangle must have two or three acute angles. A triangle always has interior angles that sum to 180 degrees. If a triangle had only one acute angle, the sum of its angles would be more than 180 degrees, which is not possible.
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 triangle has 3 acute angles and 3 equal sides?
Any triangle that has three equals sides must have three acute angles and is equilateral.
How many acute angles in an equilateral triangle?
An equilateral triangle has all three angles equal and they must sum to 180 degrees. So 180 divided by 3 is 60 which is an acute angle. There are three acute angles in an equilateral triangle.
A triangle with two acute angles must be a right angle?
No. The three angles in a triangle, in plane Euclidean geometry, must add to 180 degrees. Acute angles are less than 90 degrees. Therefore you may have a triangle with three angles which are 60 degrees for instance.
Are the the angles in a triangle acute?
In plane geometry at least two angles must be acute in a triangle.
Is a scalene triangle always an obtuse triangle.?
A scalene triangle can have an obtuse angle and two different acute angles or three different acute angles but all angles in a triangle must add up to 180 degrees.
Does an isosceles triangle have to have three acute angles?
No. The angle that isn't acute must be the unique angle, though.
Can a triangle have 1 obtuse angle and 2 acute angles?
A triangle can have one obtuse angle and two acute angles. The sum of all three angles must equal 180 degrees.
Can a triangle have an acute angle?
Yes it can. A triangle must have at least two acute angles.
What is an acute equilateral triangle?
An equilateral triangle must be acute because each angle is equal to 60 degrees. If all three angles are less than 90 degrees then a triangle is acute.
What is the least amount of angles and acute triangle can have?
If you meen the three angles, all tirangles angles add to 180 degrees. But all of the angles must be different, that's what makes it an acute triange. So three.
Can a triangle have one acute angles?
nope. if it did, the two other ends wouldn't be able to meet with obtuse angles. A triangle must have two or three acute angles. A triangle always has interior angles that sum to 180 degrees. If a triangle had only one acute angle, the sum of its angles would be more than 180 degrees, which is not possible.
Why do all triangles have acute angles?
A triangle is a three-sided figure with three angles, two or three of which (depending on the triangle) must be acute angles. The sum of all of the angles has to equal 180° - no more, no less. An acute angle is an angle of less than 90°. If one of the angles of a triangle is 90° or more (it is a right angle or obtuse angle) the SUM of the other two angles cannot exceed 180° minus the degree of the first angle. Therefore the two remaining angles must be less than the first angle, which means that they have to be acute angles.
