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.)
A triangle with an acute angle.An acute triangle has all three angles less than 90 degrees.
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.
A triangle can have a corner of any measure greater than zero and less than 180 but the three angles must add up to 180 degrees.
The word 'Triangle' means 'three angles' more archaicly, a 'trigon'. It is also a collective noun for different shapes of triangles. OBTUSE ; one of the angles in a triangle is greater than 90 degrees. By summation it means the other two angles musr be less than 90 degrees, SCALENE ; All the sides and all the angles are different. This type of triangle my exhibit obtuse characteristics. ACUTE ISOSCELES ; All the angles are less than 90 degrees. Two of the three angles are the same size, and two of the three sides are the same length. NB It is possible to have an OBTUSE Isosceles. triangle. There is a fourth type of triangle, which is a 'RIGHT ANGLED' triangle. In this case one angle is 90 degrees. This type of triangle may be ISOSCELES or SCALENE. NB For ALL triangles, drawn on a plane surface, the sum of the interior angles is ALWAYS 180 degrees. However, for triangles drawen on a curved surface; a sphere , the EARTH, the sum of the interior angles may add up to 360 degrees.
This would be an acute triangle. If all three angles are 60 degrees, then it is equiangular.
Yes. An acute triangle has three angles that individually are less than 90 degrees. Remember you can add the internal angles together in a triangle and they will always add up to 180 degrees.
A scalene triangle
an acute triangle is a triangle that has?
An acute triangle is one in which all interior angles are less than 90 degrees.
The sum of the angles of a triangle is 180 degrees so it cannot have three 90 degrees. An acute angle is an angle less than 90 degrees. An acute triangle is one in which all the angles are acute.
No. In every possible triangle, the three angles always add up to 180 degrees.
Acute scalene triangle: A triangle with three sides of different lengths and all three angles less than 90 degrees. Acute isosceles triangle: A triangle with at least two sides of equal length and all three angles less than 90 degrees. Acute equilateral triangle: A triangle with three equal sides and all three angles measuring less than 60 degrees.
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.
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.)
Each of the 3 interior angles is less than 90 degrees
