No. By definition, an acute triangle is a triangle where all three angles are <90 degrees. Therefore, an equilateral triangle, where all the angles are 60 degrees would qualify as an acute triangle.
The sum of all of the angles of a triangle will ALWAYS be 180 degrees.
In an equilateral triangle, all of the angles are equal, which makes them all 60 degrees. Therefore, all three angles are acute.
An acute triangle.
The interior angles of a triangle all add up to 180 degrees.
A triangle, all of whose angles are acute.A triangle, all of whose angles are acute.A triangle, all of whose angles are acute.A triangle, all of whose angles are acute.
A triangle with 3 acute angles is an acute triangle. All the angles in an acute triangle are acute.
No. By definition, an acute triangle is a triangle where all three angles are <90 degrees. Therefore, an equilateral triangle, where all the angles are 60 degrees would qualify as an acute triangle.
False - and false ! Not ALL angles are right-angles - and a triangle has THREE sides !
The sum of all of the angles of a triangle will ALWAYS be 180 degrees.
Sum of angles in a triangle is 180
A scalene triangle has all sides and angles in different sizes.
In an equilateral triangle, all of the angles are equal, which makes them all 60 degrees. Therefore, all three angles are acute.
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.)
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.
If it is an equilateral triangle all the angles would be 90 degrees or right angles
If all sides of a triangle are of equal length, then all the angles are the same. The sum of the angles of a triangle is 180 degrees. If all 3 angles are the same, divide 180 by 3 = 60 degree angles.
