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...
Is all acute triangles similar?
Only if they have the same angles

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...
Can an acute triangle be an right triangle?
No, acute triangles must have all angles less than 90 degrees.
Is the Pythagorean theorem is true for all similar triangles?
Only right triangles.
Is there an acute right triangle?
All right angle triangles have a 90 degree angle and 2 acute angles that add up to 90 degrees.
Are all right triangles similar?
If one corner is right, the other corners are together 90 degrees. So they're both still variable. So: no not all right triangles are similar
Which shapes have acute angles?
All triangles have at least two acute angles. Acute triangles have three. Rhomboids also have two acute angles.
Can The law of cosines can only be applied to acute triangles?
No, it applies to all triangles.
