First of all, a triangle cannot be obtuse and acute at the same time. Sometimes height can even be outside a triangle. Because all the angles in a triangle add up to 180, the other two angles have to be acute (less than 90). In the case of a right triangle, two of the altitudes are actually sides of the triangle. Hence, if one angle of the triangle is obtuse, then the other two angles with always be acute. An equilateral triangle can never be obtuse. Since an equilateral triangle has equal sides and angles, each angle measures 60, which is acute. An equilateral triangle cannot be obtuse. No, because the sum of three angles of a triangle is 180 degree & sum of any two obtuse angles is always more than 180 degree. The examples of acute angle degrees are 12, 35, 48, 65, 80, 89. Drag the protractor and rotate it using arrow keys. For acute triangles you can get this from the law of sines: , so if a>b then a/b>1 and so therefore sin (A) > sin (B). images/protractor-angle.js Be careful which angle you read from the protractor. This statement can be interpreted as applying only to acute triangles. In any triangle, if one of the sides is produced, then the exterior angle is greater than either of the interior and opposite angles. Answer: Since all its angles are less than 90, it is an acute triangle. Well, plug in the values and you get the length of the side next to the 31 angle (or opposite the 42 angle): b = 180 sin 42 / sin 31 234.
