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 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
Triangles may be right triangles equilateral triangles acute or obtuse triangles
no
Triangles
In a right triangle there is only one acute angles.
No, scalene triangles can be obtuse, right or acute triangles. A 3 - 4 -5 right triangle (lengths of the sides) is one example of a right-scalene triangle. In fact, with the exception of the [45°, 45°, 90°] right triangle (which is isosceles) all other right triangles are scalene.
yes a isosceles triangle has a right,obtuse and acute angle.
No because only right angle triangles have 2 acute angles
All right angle triangles have a 90 degree angle and two acute angles that add up to 90 degrees
No. All three angles of an acute traingle are less than 90 degrees, so it cannot be a right triangle. The only similarity between them is that right angle triangle has 2 acute angles while acute triangles has 3 acute angles
Yes all equilateral triangles are acute triangles, but not all acute triangle are equilateral triangles.
