Actually, you cannot conclude anything this way, at least not in regular geometry. For instance, in a "perfect triangle," all 3 angles are acute. In a right triangle, one is a right angle and the other two are acute. It is also possible to have an obtuse angle and two acute angles. The thing is, the 3 angles must add up to 180 degrees.
There may be either 2 or 3.If there are only 2, the third angle is equal to or greater than 90 degrees.(the sum of the three angles must equal 180 degrees)If there are 3, the triangle is called an acute triangle.
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.
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.
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.
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.
Every triangle must have at least two acute angles. The third one can be acute, right (90 degrees), or obtuse.
No. In fact, if one of the angles is not acute (a right angle or obtuse), the other two must be acute.
In plane geometry at least two angles must be acute in a triangle.
Yes, you have two congruent angles in each triangle, one right and one acute so the third angles must be equal also.
Yes it can. A triangle must have at least two acute angles.
A right angled triangle has one angle that is 90 degrees. The other two must be acute and may (but need not) be equal to one another. An acute triangle has all its angles less than 90 degrees. They may be all the same, two of them the same or all different. An isosceles triangle has two angles the same (and hence acute). The third angle can be acute, right or obtuse. A scalene triangle has three unequal angles. Two of them must be acute but the third may be acute, right or obtuse.
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.
Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle. If they are both 45° then the third angle is a right angle and if they are both greater than 45° then the third angle is an acute angle.
The sum of two acute angles of a right triangle must equal 90 degrees.
There may be either 2 or 3.If there are only 2, the third angle is equal to or greater than 90 degrees.(the sum of the three angles must equal 180 degrees)If there are 3, the triangle is called an acute triangle.
No, in fact no triangle can have two right angles. The sum of all interior angles of any triangle is 180 degrees. All triangles must have three angles. A right angle is 90 degrees. So if a triangle has two ninety degree angles, there would be no third angle. An acute triangle has all three angles less than 90 degrees. The most common acute triangle is the equilateral 60-60-60 degree triangle.
Every triangle must have either 2 or else 3 acute angles. The least possible is 2.
