Question

can all the angle of quadrilaterals be acute angle give reason

Answer 1

No it's not possible.......

Because if all the angles will be acute, Sum of all angles will be less than 360°, which is not possible According to angle sum property of quadrilateral.

First angle < 90 --------(1)

Second angle < 90 ------(2)

Third angle < 90 -------(3)

Fourth angle < 90 --------(4)

On adding equation 1, 2, 3 and 4, we get

Sum of four angles < 360°

But it is not possible..

Answer 2

no it can not possible because quadrilateral have 4 angle of sum 360° and then scan angle got =90o° above so it can possible to get all angle acute in quadrilateral
