No. An acute triangle only has angles less than 90 degrees. A triangle with a 130 degree angle is obtuse.
Yes, but a triangle is acute only if all three of its angles are acute (< 90o).An isosceles triangle can be an acute triangle, but it doesn't have to be.An acute triangle can be an isosceles triangle, but it doesn't have to be.That depends on the sizes of its angle because an isosceles triangle has 2 equal sides and 2 equal angles which could be 70 degrees, 70 degrees and 40 degrees which are all acute angles that add up to 180 degrees.
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.
Only when it has 3 equal acute angles of 60 degrees
A triangle with all angles measuring less than 90 degrees?That's an 'acute' triangle.
There are three acute angles in an acute triangle and they add up to 180 degrees.
0-89 degrees
Less than 90 degrees.
Less than 90 degrees.
An acute triangle can have as much as 3 acute angles providing that they all add up to 180 degrees.
A triangle can have 3 acute angles that add up to 180 degrees
If the triangle is less than 90 degrees, it is an acute triangle
An equilateral triangle has 3 equal interior acute angles of 60 degrees
No. An acute triangle only has angles less than 90 degrees. A triangle with a 130 degree angle is obtuse.
An equilateral triangle has 3 equal acute angles of 60 degrees and it has 3 lines of symmetry.
A triangle with an acute angle.An acute triangle has all three angles less than 90 degrees.
