yes. to be and acute angle, all angles must be acute. Obtuse angles only one angle has to be obtuse. Right angles only need one too. Acute has to have every angle to be acute, if one angle is obtuse or right, it's automatically no an acute Angle anymore.

What shapes have straight angle?

It's not that easy to answer because a straight angle is like a straight line and I think that it would be on either every or none of the shapes that I would know of. Any shape has a right, obtuse,or acute angle. So, I am guessing that no shapes have straight angles. or that a straight angle is in every angle which is not true.


Are all equallateral triangles acute?

-- An 'acute triangle' is a triangle in which each of the three interior angles is an acute angle. -- Each of the three interior angles in every equilateral triangle is a 60-degree angle. -- Any angle of less than 90 degrees is an acute angle. -- It sure looks like every equilateral triangle does fit the definition of 'acute triangle'.

Does Every right triangle has one right angle one acute angle and one obtuse angle?

No it is impossible for a right triangle to have an obtuse angle therefore it will have one right angle and two acute angles.


Is the complement of an acute angle an acute angle?

A complement of an acute angle must be an acute angle. An acute angle is an angle whose measure is more than 0 degrees but less than 90 degrees. For example, even if the angle was the minimum 1 degree, the complement is still 89 degrees, which is still acute. Therefore, any combination of a complement of an acute angle MUST be acute.


If an acute angle of one right triangle is congruent to an angle of a second triangle then are the triangles similar?

true.


Which shape has only two acute angles?

"z" has two acute angles a triangle can have 3 acute angles but also will have a angle >= 60degrees acute (also note for every acute angle a obtuse angle is formed the sum of the obtuse and acute angle will = 360) because of this a arrow is the only shape with two acute angles and 1 obtuse


A triangle with one obtuse angle must also have two acute angles?

True


What is an acute angle?

An acute angle is an angle that measures less than 90 degrees. See the related link, "Acute Angle Pictures" for a diagram of some acute angles.


Does an acute has 17 degrees?

An acute angle is an angle less than 90°. So an angle of 17° is an acute angle.
