Which triangle is surely an acute angled triangle?

equilateral triangle
An equilateral triangle is a triangle with all three angles and sides equal. If all a triangle’s angles are equal, they all must measure 60 degrees, adding up to 180 degrees total. Since all angles are acute, or less than 90 degrees, an equilateral triangle is also an acute triangle.

Can all the angles of a triangle be acute Yes or no?

Yes, all triangles have at least two acute angles. Acute angles are angles that measure less than 90 degrees, while obtuse angles measure greater than…

How many angles of a triangle will be always acute?

three acute angles
An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°).

Can a triangle have all angles less than 60 degree?

A triangle with all the three angles less than 60∘ is not possible, as the sum of all the angles of a triangle is 180∘​.

What is an oblique triangle?

An oblique triangle is any triangle that is not a right triangle. It could be an acute triangle (all threee angles of the triangle are less than right angles) or it could be an obtuse triangle (one of the three angles is greater than a right angle).

Does a triangle always have 3 acute angles?

A triangle where all three internal angles are acute (less than 90 degrees). In any triangle, two of the interior angles are always acute (less than 90 degrees)*, so there are three possibilities for the third angle: Less than 90° – all three angles are acute and so the triangle is acute.

Can a triangle have more than 2 acute angles?

The definition of acute angle is that the range for the angle has to be 0∘<α<90∘. Therefore, a triangle can have two acute angles as the sum of those two angles becomes less than 180∘.

What is reflex angle?

noun Geometry. an angle greater than 180° and less than 360°.

What is less than a right angle?

An acute angle is an angle less than a right angle.

Can you have a triangle with 3 angles less than 60 degrees yes or no?

A triangle cannot have neither all the angles less than 60 degree nor greater than 60 degrees.
