The smallest angle in a triangle is 50 degrees. This triangle is () triangle A. Acute angle B. right angle C. obtuse angle D. indeterminate
180 ° - 50 ° = 130 °; the sum of the other two angles is 130 ° and the smallest internal angle is 50 ° suppose that there is another one of the other two angles is 50 ° and the other one is 130 ° - 50 ° = 80 ° and the largest internal angle can only be 80 ° so the three angles of the triangle are acute angles and the triangle must be an acute angle triangle
If the smallest angle in a triangle is 46 degrees, then this is a triangle______ A triangle
Suppose that one of the other two angles is 46 °, then the maximum angle should be less than or equal to 180 ° - 46 ° × 2 = 88 ° and this triangle must be an acute angle triangle
The maximum angle of a triangle is three times of the minimum angle, and the other angle is two times of the minimum angle. How many degrees are the three angles
Minimum angle = 180 ° / (3 + 2 + 1) = 30 °
Maximum angle = 30 °× 3 = 90 °
The third triangle = 30 °× 2 = 60 °
