squares, right triangles, rectangles
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
All triangles that are not right triangles.
Triangles without right angles are:- Scalene triangles Obtuse triangles Isosceles triangles Equilateral triangles
Isoceles triangles and right triangles have 2 corresponding equal angles three equal corresponding angles are equilateral triangle
Acute triangles have angles less than 90 degrees. Right triangles have 90 degree angles.
INCORRECT: No because there is a obtuse triangle and a right triangleCORRECT ANSWERYes all triangles have at least two acute angles. Obtuse triangles and right triangles also have at least two acute angles. They are called obtuse triangles and right triangles because by definition they are triangles with ONE obtuse angle and ONE right angle. So therefore they both have 2 acute angles. Also for an acute triangle, it would have 3 acute angles.
Triangles may be right triangles equilateral triangles acute or obtuse triangles
It depends
Triangles
yes they can,they can have right angles because if you turn it then you would have a right angle
In a right triangle there is only one acute angles.
