Yes. In fact, all triangles MUST have at least two acute angles.
mmmmmmmmmmm
Two. Two acute angles in a right triangle.
In Euclidean geometry a right angle triangle has two acute angles. All others have three.
A triangle with 3 acute angles is simply called an acute triangle.An example is an equilateral triangle, which has three angles of 60° (acute).
An Acute Triangle
No, in fact no triangle can have two right angles. The sum of all interior angles of any triangle is 180 degrees. All triangles must have three angles. A right angle is 90 degrees. So if a triangle has two ninety degree angles, there would be no third angle. An acute triangle has all three angles less than 90 degrees. The most common acute triangle is the equilateral 60-60-60 degree triangle.
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 plane geometry at least two angles must be acute in a triangle.
In a right angled triangle the two other angles are acute.
In a right angled triangle the two other angles are acute.
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
a right triangle has one right angle and two acute angles
Answer: Yes, because of the two angles have to be exactly equal in order to be isosceles. And no isosceles has 3 acute angles and then it will be equilateral triangle Answer: No, the isosceles triangle can either have two acute angles, or all three can be acute.
The sum of two acute angles of a right triangle must equal 90 degrees.
