360 - (90 + 100 + 120)...
A quadrilateral is a 4 sided shape whose 4 interior angles add up to 360 degrees.
No. It can so on your paper you cant put it cant have 4 angels with a different measure
4
no its false
It can, but usually doesn't.
A quadrilateral may have all 4 angles different if it is not a square, rectangle, rhombus, rhomboid, rectangular trapezoid, isosceles trapezoid, or parallellogram.
It is possible, but parallelograms do not. Some quadrilaterals do.
Yes. For example a quadrilateral can have angles 80°, 85°, 95°, 100 The only requirement is that the sum of the 4 angles is 360°.
No. A triangle has 3 sides. A quadrilateral has 4 sides.
4 right angles. A right angle is a 90 Degree measure like for example: L <---- 90 degree measure. And the rectangle has 4 angles like that so it means it has 4 right angles.
4 right angles, by definition, are four angles of the same measure, and therefore must be congruent angles.
