Yes . Triangle have right acute and obtuse angle except compelete angle.
It could be a right triangle if it has a right angle (90 degrees). If it does not have a right angle, then it is an acute triangle.
What is a 79 degree of a third angle of a triangle
If you are classifying triangles by their angles, an obtuse triangle has one obtuse angle and two acute angles. A triangle can have at most one obtuse angle. If the two acute angles are congruent, the triangle would also be isosceles.
In a triangle the smallest angle is always opposite the shortest side. It will always be an acute angle.
no
Yes. Every triangle with an obtuse angle must have two acute angles.
Yes. This is called an acute angle. Yes. This is called an acute angle.
no
YesAcute =
90
yes, it only needs one acute angle out of the three to make it an acute triangle.
An acute triangle.
Yes. In this case a triangle is called an acute triangle.
Yes. For example an equilateral triangle has 60 degrees in each angle (180 divided by 3 is 60) and since an acute angle is an angle with degrees less than 90, all three of the 60 degree angles are acute. Therefore, you can have a triangle with 3 acute angles.
No, an acute triangle must have all 3 angles under 90 degrees. A triangle can have an acute angle and still be a right triangle or an obtuse triangle.
'a' and 'b' must both be acute, complementary angles.
