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

What are right angled scalene triangles?
Right triangles have one right angle. Scalene triangleIs have sides of unequal length. Right scalene triangles combine those aspects.
Do all acute triangles have only one acute angle?
No. All triangles MUST have at least two acute angles.
