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.

Is this statement true or false A right triangle is also acute.?
False
True or false a right triangle cannot be an obtuse triangle?
true
A right triangle can be isosceles.True or False?
True
True are false A triangle with sides lengths 40 75 and 84 are a right triangle?
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.
Is this statement true or false A right triangle is also acute.?
False
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.
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
'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...
Is this statement true or falseThe triangle is a right triangle?
false
True or false a right triangle cannot be an obtuse triangle?
true
When two right triangles are similar if an acute angle of one triangle is congruent to an acute angle of the other triangle?
this is true
A right triangle can be isosceles.True or False?
True
True are false A triangle with sides lengths 40 75 and 84 are a right triangle?
False.
A triangle can have two right angles true or false?
false
A right angle triangle has one 90 true or false?
True. It could not have 2 right angles, because the combined angles of a triangle equal 180 and 2 right angles would leave the final side at 0 degrees.
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.
