In a quadrilateral (four sided polygon), the four angles will add up to 360°.
No because the 4 interior angles of any 4 sided quadrilateral always add up to 360 degrees.
Use a protractor but in general thr 4 interior angles of any quadrilateral add up to 360 degrees
It is just an irregular quadrilateral.
Any angle <360 degrees is possible, though it would be a concave quadrilateral if the angle were greater than 180 deg.
Quadrilaterals have a constant total angle measurement of 360 degrees
To find the measurement of the fourth angle in a quadrilateral when three angles are given, you can use the property that the sum of all angles in a quadrilateral is always 360 degrees. Given that the three angles are 90, 145, and 78 degrees, you can add these together and subtract the sum from 360 to find the measurement of the fourth angle. Therefore, the fourth angle would be 360 - (90 + 145 + 78) = 47 degrees.

In a quadrilateral (four sided polygon), the four angles will add up to 360°.
For any quadrilateral (i.e. 4-sided figure), the angles will add up to 360 degrees. Since an obtuse angle is any angle with a measurement over 90 degrees, it is possible to have a quadrilateral with 3 obtuse angles. The fourth angle, however, must be acute (i.e. smaller than 90 degrees). Having 3 obtuse angles is not a requirement, however, for a quadrilateral.
No because the 4 interior angles of any 4 sided quadrilateral always add up to 360 degrees.
Sum of angles in a quadrilateral is 360° Three angles sum to 80° + 120° + 65° = 265° Therefore the missing fourth angle is 360° - 265° = 95°
a quadrilateral with no right angle is?
A chevron (arrowhead) is a quadrilateral with one angle of more than 1800.
Use a protractor but in general thr 4 interior angles of any quadrilateral add up to 360 degrees
Well, honey, a quadrilateral with 4 obtuse angles is simply not possible in this universe. You see, the sum of the interior angles of any quadrilateral must add up to 360 degrees. So, having 4 obtuse angles, each measuring more than 90 degrees, would blow that total out of the water. It's like trying to fit into your high school jeans after Thanksgiving dinner - just not gonna happen, sweetheart.
is an exterior angle of a quadrilateral always sometime or never 90 degrees
