Actually, you cannot conclude anything this way, at least not in regular geometry. For instance, in a "perfect triangle," all 3 angles are acute. In a right triangle, one is a right angle and the other two are acute. It is also possible to have an obtuse angle and two acute angles. The thing is, the 3 angles must add up to 180 degrees.
A triangle is not an angle. A triangle is made of three angles. -- All three of them can be acute, but they don't need to be. -- One of them can be obtuse but doesn't need to be. -- One of them can be a right angle but doesn't need to be. -- If any angle in the triangle is right or obtuse, then the other two need to be acute.
Yes providing the other 2 angles are acute
Sounds true to me, all three angles are congruent...
No, it is not possible to draw a reflex angle where the other angle formed by the arm is acute. A reflex angle measures between 180 and 360 degrees, while an acute angle measures less than 90 degrees. Therefore, the other angle formed by the arm in a reflex angle scenario would have to be obtuse, measuring between 90 and 180 degrees.
Roads don't always form an acute angle, they can form a right angle. If you are really picky, you might say that they can never form a perfect right angle, so two of the angles formed must be acute (and the other two obtuse).
The question appears to relate to the angles of a triangle. 1) If angle 3 is acute then the other two angles can also be acute. In the case of an equilateral triangle all three angles are equal and acute. 2) If angle 3 is acute and one other angle is obtuse then the remaining angle is acute. 3) If angle 3 is acute and one other angle is a right angle then the remaining angle is acute.
Acute or obtuse: Yes. Straight: No.
Yes providing that the other 2 angles are acute
A right triangle is a triangle with one of its angles being 90o. The requirements for the other two angles are that they both be acute and total to 90o. Therefore, the largest possible acute angle in a right triangle is 89.99999...o.
Yes
That depends on the sizes of the other 2 angles if it's a right angle triangle then the other acute angle would be 70 degrees.
Yes. In this case a triangle is called an acute triangle.
