If there were less than two acute angles, there would be two (or more angles that were 90 degrees or more. Then the sum of the three angles of the triangle would be more than 180 degrees. But this is not possible because the interior angles of a triangle sum to 180 degrees.
yes an obtuse triangle has two acute angles
A right angled triangle can only have two acute angles.
Two. Two acute angles in a right triangle.
In a right angled triangle the two other angles are acute.
In a right angled triangle the two other angles are acute.
In plane geometry at least two angles must be acute in a triangle.
A scalene triangle could have three acute angles, one right angle and two acute angles, or one obtuse angle and two acute angles.
A triangle with 3 acute angles is an acute triangle. All the angles in an acute triangle are acute.
An acute triangle has three interior acute angles An obtuse triangle has one obtuse and two acute interior angles
Yes it can. A triangle must have at least two acute angles.
The sum of two acute angles of a right triangle must equal 90 degrees.
No triangle is never acute in the sense that every triangle has at least two acute angles.
