Similarities between these and all triangles are:

They all have 3 sides and 3 angles. The sum of the three angles adds up to 180°.

An acute angle is less than 90 degrees. An acute triangle has all three sides are acute.

An obtuse angle is more than 90 degrees. An obtuse triangle has one angle which is obtuse, and because of the 180° rule above, the other two angles will be acute.

So all triangles will have at least two acute angles.

No, an obtuse triangles has one obtuse angle and two acute angles. If a triangle has an obtuse angle, it is considered obtuse and cannot be acute.

Are triangles always regular?

Of course not! There are obtuse and acute triangles.

Do all triangles have two acute 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.

Can an acute and obtuse triangle be similar?

No. Similar triangles have all the same angles. An acute triangle can never have an obtuse angle, so the two cannot be similar.

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

What triangle has at least one obtuse angle?

-- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it . -- Right triangles, acute triangles, and equilateral triangles don't have any obtuse angles in them.
