2. Could a quadrilateral have 4 obtuse angles? Yes/No then Explain the answer.

Solution

Dear Student

Thank you for using Chegg !!

a) Can a parallelogram have right angles? Yes/No then Explain the answer.

A parallelogram is a quadrilateral with opposite sides parallel to each other. Hence square & rectangle are perfect examples of a parallelogram.

Now since all 4 angles of parallelogram are 90 Degree, Hence the given statement is True .

b) Could a quadrilateral have 4 obtuse angles? Yes/No then Explain the answer.

Kindly note that sum of all the angles of a quadrilateral is 360 degrees.

Since obtuse angles are those having angle more than 90 degree.

If all 4 angles of quadrilateral are obtuse, implies sum of all 4 angles is more than 360 degrees

which is not possible.

Hence the given statement is cannot be true.

So No, A quadrilateral cannot have all four angles as obtuse.
