Can a right-angled triangled have acute angles in it? |
|
Answer» right TRIANGLE can, and MUST, have exactly TWO acute angles. ... As a right triangle has one angle equal to 90∘ , this means the sum of the remaining two angles must be 180∘−90∘=90∘ . THUS, both of the remaining two angles must have a measure less than 90∘ and therefore must be acute. |
