I'm not sure I understand your actual question, but what you are actually asking with the wording is false.

Two 30 degree angles would both be acute angles whos sum would only create another acute angle of 60 degrees.

But if you have 2 acute angles, then the third would have to be obtuse to form a triangle.

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


Can a quadrilaterals have 4 acute angles?

No, because the sum of all the angles is always 360 degrees. If 3 of the angles are acute (less than 90), then the sum of these must be less than 270. Therefore the remaining angle must be obtuse (greater than 90), so that the sum of all 4 is 360.


How many acute angles can be in a quadrilateral?

A quadrilateral can have 0 to 3 acute angles, but never 4:A rectangle and a square are both quadrilaterals with four right angles, hence they have no acute angles.A kite-shaped figure can have one acute and three obtuse angles, or three acute and one obtuse angles.A parallelogram and a rhombus have two acute and two obtuse angles.The sum of the interior angles of any quadrilateral is 360º; thus it would be impossible for all angles to be acute (less than 90º each)


How are acute and obtuse triangles the same?

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.


How many obtuse and acute angles can be in a right triangle?

In a right triangle, one of the angles is already given - 90 degrees. Since the angles of a triangle must add up to 180 degrees, the other two must always add up to 90, so that after you add the right angle, the sum is 180. So both of the other angles have to be less than 90. That is, they both must be acute. So there can be NO obtuse angles in a right triangle. There are EXACTLY two acute angles in a right triangle.

The sum of two acute angles is something always or never an obtuse?

The sum of two acute angles is sometimes an obtuse angle because, acute angles can measure from 10 to 90 degrees. Two 30 degree angles would both be acute whose sum would only create another acute angle of 60 degrees. But, two80 degree angles would both be acute angle whose sum would only create an obtuse angle.


Can a triangle have 2 obtuse angles and one acute angle?

Nope, only one obtuse angle in a triangle is possible. The sum of the interior angles of a triangle is always 180º and an obtuse angle is larger than 90º. Thus the sum of two obtuse angles would be greater than 180º even without including an acute angle.


Are the angles on a heptagon acute obtuse or right?

They can be acute, obtuse or right - or even reflex. The only condition is that their sum is 900 degrees.

Can a triangle have 1 obtuse angle and 2 acute angles?

A triangle can have one obtuse angle and two acute angles. The sum of all three angles must equal 180 degrees.


What is the difference between 5 acute 2 obtuse and 5 right angles?

There are fewer obtuse angles than the other two kinds. There are the same number of acute and right angles and so the sum of the measures of the acute angles will be less than 5 right angles. The sum of two obtuse angles will be less than 5 right angles but may be less than, equal to, or more than 5 acute angles.


Can a triangle have one acute angles?

nope. if it did, the two other ends wouldn't be able to meet with obtuse angles. A triangle must have two or three acute angles. A triangle always has interior angles that sum to 180 degrees. If a triangle had only one acute angle, the sum of its angles would be more than 180 degrees, which is not possible.


Can a quadrilaterals have 4 acute angles?

No, because the sum of all the angles is always 360 degrees. If 3 of the angles are acute (less than 90), then the sum of these must be less than 270. Therefore the remaining angle must be obtuse (greater than 90), so that the sum of all 4 is 360.


If a triangle has one obtuse angle then the other two angles are acute?

Yeah, they have to be. The sum of the interior angles of a triangle is always 180. If one angle is greater than 90, then the remaining two's sum cannot be.


What angle is a triangle?

A triangle has three angles. The sum of these 3 angles = 180°. At least two of the 3 angles will be acute angles (less than 90°). The third angle can be acute, or a right angle (equal to 90°) or obtuse (between 90° and 180°). Triangles can be categorized by the angles (acute, right or obtuse).


Is the sum of the measures of two acute angles equal to the measure of an obtuse angle?

Only if their sum is greater than 90 degrees
