The sum of the angles in a quadrilateral is always 360 degrees. Given the three angles measuring 60, 120, and 90 degrees, their sum is 60 + 120 + 90 = 270 degrees. To find the fourth angle, subtract this sum from 360 degrees: 360 - 270 = 90 degrees. Therefore, the measurement of the fourth angle is 90 degrees.
The exterior angle of a quadrilateral can vary depending on the shape of the quadrilateral. It is not fixed at 90 degrees; rather, the sum of the exterior angles of any polygon, including a quadrilateral, is always 360 degrees. Therefore, while some exterior angles of specific quadrilaterals may be 90 degrees, others will be different.
A quadrilateral can have two right angles and still not be a rectangle, if one side is oblique (neither right nor parallel) to the others, but three right angles force the fourth, and you have a rectangle.
Depends what sort of quadrilateral. For a square and rectangle, it's 90 all the way, but with all others, it varies.
quadrilateral is the only term I know of in geometry. Others...Quadriceps Quadruples etc.
110 degrees.
360 - (80 + 120 + 65) ie 95o
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°
The sum of the angles in a quadrilateral is always 360 degrees. Given the three angles measuring 60, 120, and 90 degrees, their sum is 60 + 120 + 90 = 270 degrees. To find the fourth angle, subtract this sum from 360 degrees: 360 - 270 = 90 degrees. Therefore, the measurement of the fourth angle is 90 degrees.
The answer would be 90 degrees, because the quadrilateral's angles should add up to 360 degrees. 360 - (60 + 120 + 90)= 90 120 + 60 = 180 + 90 = 270 + 90 = 360

A quadrilateral is a 4 sided closed shape, like a square or rectangle. There's also a rhombus (tilty, squished square), diamond, parrallelogram, and many others. As long as it has 4 sides and is closed, it's a quadrilateral. Quad means 4. Every quadrilateral has 4 angles inside, as well as 4 sides. An easy example is a square, or rectangle. Pick up a textbook if you're having trouble visualizing, or draw a square on a piece of paper. Squares (and rectangles) have four 90 degree angles. 4*90 = 360 degrees in a quadrilateral. Side note: The sum of the angles in a triangle is 180 degrees. What about shapes with 5 sides... 6 sides... or more? Do you think a 5-sided shape will have 360 degrees in angle sums? More or less?
A square.Or even a rectangle.A hexagon.and many others have at least one.but if your question is what quadrilateral shape has ONLY one.then ur answer is a Trapazoid.
