Depends on the exact measurements. If, for example, the two acute angles are ten and twelve, the remaining angle would be one hundred fifty-eight, which is obtuse. But if the acute angles are thirty and eighty-nine, then the remaining angle would be sixty-one, which is also acute.

If two angles of a triangle are acute must the the third angle always be acute?
No. In fact, if one of the angles is not acute (a right angle or obtuse), the other two must be acute.
What type of angle does a triangle have?
A triangle has at two acute angles and the third angle is either an acute angle, a right angle or an obtuse angle.
What type of angles are in an Isosceles triangle?
There are two equal acute angles. The third angle can be acute, right or obtuse.
If two angles of a triangle are acute then the third angle .?
... may be acute, right, or obtuse.
Has an isosceles triangle have an obtuse angle?
Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle. If they are both 45° then the third angle is a right angle and if they are both greater than 45° then the third angle is an acute angle.
If two angles of a triangle are acute then the third angle must be?
It can be either acute or obtuse. An acute angle is less than 90 degrees and all 3 angles add to 180 degrees. For example, If two angles are 60 degrees (acute) then the 3rd is 60 degrees (acute). If two angles are 30 degrees (acute) the 3rd is 120 degrees (obtuse).
Can an triangle have 2 acute angles?
yes they can! the third angle would be very obtuse.
Find the third angle of a right triange if the measure of one of the angles is 25 degrees?
a triangle has 180º so 180-90-25= 65
What angles does the acute isosceles have?
The two equal angle can have any value between (but not equal to) 45 and 90 degrees. The third angle is then 180 - 2*one of these angles.
If two angles of a triangle are acute then the third must be?
Actually, you cannot conclude anything this way, at least not in regular geometry. For instance, in a "perfect triangle," all 3 angles are acute. In a right triangle, one is a right angle and the other two are acute. It is also possible to have an obtuse angle and two acute angles. The thing is, the 3 angles must add up to 180 degrees.
Are two right triangles similar if an acute angle of one triangle is congruent to an acute angle of the other triangle?
Yes, you have two congruent angles in each triangle, one right and one acute so the third angles must be equal also.
If two angles are acute then the third angle is what?
obtuse Actually it could be acute, right, and/or obtuse.. if that makes sense..
