Do triangles have at least one right angle?
Triangles can be classified by their sides or their angles. When classifying them by their angles, triangles are called: acute triangles - all three angles are acute (less than 90º) right triangles - one right angle (90º) and two acute angles obtuse triangles - one obtuse angle (larger than 90º) and two acute angles
Triangle in which all of the angles are acute angles?
They are possible - unlike plane triangles in which all of the angles are right angles, obtuse or larger.
A triangle with 2 acute angles?
All right angle triangles have 2 acute angles and one 90 degree angle.
What is the least number of angles an acute triangle can have?
All acute triangles have 3 interior angles and 3 exterior angles. This is true for all triangles.
Are all acute triangles equilateral triangles?
No, but all equilateral triangles are acute. Acute: All angles of the triangle are less than 90 degrees. Equilateral: All angles of the triangle are 60 degrees.
