Do all triangles have two acute angles?
INCORRECT: No because there is a obtuse triangle and a right triangleCORRECT ANSWERYes all triangles have at least two acute angles. Obtuse triangles and right triangles also have at least two acute angles. They are called obtuse triangles and right triangles because by definition they are triangles with ONE obtuse angle and ONE right angle. So therefore they both have 2 acute angles. Also for an acute triangle, it would have 3 acute angles.
Can right triangle and acute triangles be similar?
No because a right ange triangle has a 90 degree angle and 2 acute angles whereas an acute triangle has 3 acute angles all of which are less than 90 degrees
Are all equilateral triangles acute triangles?
Yes all equilateral triangles are acute triangles, but not all acute triangle are equilateral triangles.
Are all scalene triangles acute triangles?
No, scalene triangles can be obtuse, right or acute triangles. A 3 - 4 -5 right triangle (lengths of the sides) is one example of a right-scalene triangle. In fact, with the exception of the [45°, 45°, 90°] right triangle (which is isosceles) all other right triangles are scalene.
'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...
When will two right triangles be similar?
To prove that two right triangles are similar, all you need to show is that one of them has one acute angle that's equal to one acute angle of the other one.
Is all acute triangles similar?
Only if they have the same angles

How are acute and right triangles the same?
Acute triangles have angles less than 90 degrees. Right triangles have 90 degree angles.
Can right triangle and acute triangles be similar?
No because a right ange triangle has a 90 degree angle and 2 acute angles whereas an acute triangle has 3 acute angles all of which are less than 90 degrees
Are all equilateral triangles acute triangles?
Yes all equilateral triangles are acute triangles, but not all acute triangle are equilateral triangles.
Do all right triangles have acute angles?
All right angle triangles have a 90 degree angle and two acute angles that add up to 90 degrees
Are all scalene triangles acute triangles?
No, scalene triangles can be obtuse, right or acute triangles. A 3 - 4 -5 right triangle (lengths of the sides) is one example of a right-scalene triangle. In fact, with the exception of the [45°, 45°, 90°] right triangle (which is isosceles) all other right triangles are scalene.
Do triangles have at least one right angle?
Triangles can be classified by their sides or their angles. When classifying them by their angles, triangles are called: acute triangles - all three angles are acute (less than 90º) right triangles - one right angle (90º) and two acute angles obtuse triangles - one obtuse angle (larger than 90º) and two acute angles
Can an acute and obtuse triangle be similar?
No. Similar triangles have all the same angles. An acute triangle can never have an obtuse angle, so the two cannot be similar.
'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...
What is a acute trianlge?
an acute triangle is a triangle that has corner angles all below 90 degrees. there are three types of triangles: obtuse, right, and acute. obtuse triangles have one corner angle greater than 90 degrees, right triangles have one angle equal to 90 degrees, and acute triangles have all corner angles less than 90 degrees.
