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 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.
A triangle with two acute angles must be a right triangle.?
Only if the right triangle contains a 90 degree angle and 2 acute angles that add up to 90 degrees
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.
If one angle of a triangle measures 54 degree and the other angle measures 36 degree the other angle has to be an acute angle.?
False because the 3rd angle has to be a right angle of 90 degrees because the 3 angles of any triangle add up to 180 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...
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 it true an acute angle had a measure greater than 90 degree's and less than 180 degree's?
False because an acute angle is greater than 0 and less than 90 degrees
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.
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.
Is 108 degrees an acute angle true or false?
false
Is this statement true or false A right triangle is also acute.?
False
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.
