In a right triangle, a2 + b2 = c2, where c is the longest side. If the square of the longest side is more than the sum of the other two squares, the triangle has an obtuse angle. If it is less, all angles are acute.
obtuse
None. An acute triangle is one in which all angles are acute. An obtuse triangle is one in which one of the angles is obtuse. A right angled triangle is one in which one angle is a right angle (90o)
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.)
right
Neither. An acute triangle has all angles less than 90 degrees. An obtuse triangle has one angle more than 90 degrees. A right triangle is simply just a right triangle, since it has one angle of 90 degrees.
acute , obtuse obtuse or right angle
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.
obtuse
Yes . Triangle have right acute and obtuse angle except compelete angle.
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)
A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles
there is many ways to write when classifying a triangle, you can classify it by its sides or angles. When you classify it by angles you can classify it by acute, obtuse, and right triangle. when classyfing it by sides its isosceles, equilateral, and scalene!
An acute triangle
right triangle
yes a isosceles triangle has a right,obtuse and acute angle.
None. An acute triangle is one in which all angles are acute. An obtuse triangle is one in which one of the angles is obtuse. A right angled triangle is one in which one angle is a right angle (90o)
It is an acute angle.
