Question

Which quadrilateral has no right angle

Answer 1

Squares and rectangles must all have exactly four right angles.

However, quadrilateral that don't have to have four right angles are trapezoids, parallelograms and rhombi.

trapezoids - different angles
parallelograms - 2 acute, 2 obtuse angles
rhombi - 2 acute, 2 obtuse angles

Note that a rhombus is a type of parallelogram.

Hope this helps! :)
