Question

in a quadrilateral, can all the four angles be acute ?explain the reason for your answer

Answer 1

In a quadrilateral all 4 angles add upto 360.and 4 times 90is 360..no other angle angle less than 90 can actually make a quadrilateral especially when all angles are acute because even if u take 89° which is just one less than right angle and multiply it by 4 you get 356 which is less than the total measure...
