Why is this false two acute angles side by side form one obtuse angle?

The degree of an acute angle is just less then 90 ( because it would be a right angle if it was 90). So that means it could just be a 5 degree acute angle and a 10 degree acute angle so that would only add up to 15 degrees, obviously not making it an obtuse angle.

Is a right triangle acute true or false?
False ------------------------------------ An acute triangle is one in which all angles are acute angles. An acute angle is less than 90°. A right angle is 90°, which is equal to 90° not less than 90° Therefore all the angles of a right triangle are not all acute Thus a right triangle is not an acute triangle.
What all angles are less than 90 are obtuse?
False because angles greater than 0 but less than 90 degrees are acute angles
Is it true that an obtuse triangle can have a right angle?
In Euclidean geometry, a triangle must be one of these: acute, obtuse, or right. Maybe there is a non-Euclideangeometry for which some obtuse triangles can contain a right angle, but it doesn't happen in Euclidean geometry.
Triangle can have more than one obtuse angle?
False, because a triangle can have only 1 obtuse angle
Is it false an acute triangle is always equilateral?
Yes it is correct that the statement is false. All equilateral triangles are acute, because all three angles are less than a right angle (90°). There are an infinite number of cases of acute triangles which are not equilateral.
If a triangle has an obtuse angle the in cannot be an triangle?
False because it can have 1 obtuse angle and 2 acute angles providing that all 3 angles add up to 180 degrees.
The sum of 2 acute angles is always obtuse angles?
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.
A triangle with one obtuse angle must have also have two acute angles true or false?
True and all 3 angles must add up to 180 degrees.
The bisector of a straight angle forms two acute angles?
False
Is a right triangle acute true or false?
False ------------------------------------ An acute triangle is one in which all angles are acute angles. An acute angle is less than 90°. A right angle is 90°, which is equal to 90° not less than 90° Therefore all the angles of a right triangle are not all acute Thus a right triangle is not an acute triangle.
What all angles are less than 90 are obtuse?
False because angles greater than 0 but less than 90 degrees are acute angles
Can a triangle have both an acute an a right angle true or false?
It is true because a triangle with a right angle and two acute angles is a right angle triangle.
Is it true that an obtuse triangle can have a right angle?
In Euclidean geometry, a triangle must be one of these: acute, obtuse, or right. Maybe there is a non-Euclideangeometry for which some obtuse triangles can contain a right angle, but it doesn't happen in Euclidean geometry.
If a quadrilateral is a parallelogram then its opposite angles are always supplementary?
False because it will have 2 equal opposite obtuse angles and 2 equal opposite acute angles with the 4 angles adding up to 360 degrees.
'True or false Two right triangles are similar if an acute angle of one triangle is congruent to an acute angle of the other triangle'?
Sounds true to me, all three angles are congruent...
An acute triangle is a triangle that has one 90 degree angle true or false?
False. That is a right (-angled) triangle. An acute triangle has all three angles less than 90o
Can an angle be both obtuse and isosceles true or false?
False
