The answer was Rhombus.
80 The angles in a quadrilateral add up to 360 degrees. So if 3 angles = 280 the fourth angle is 360-280 = 80
B 110 degrees C 70 degrees D 110 degrees
A chevron (arrowhead) is a quadrilateral with one angle of more than 1800.
i really dont know this problem i try to enter in but it wont actually tell me the answer
is an exterior angle of a quadrilateral always sometime or never 90 degrees
That depends on the quadrilateral. They will not all have the same measure. Even rectangles will not all have the same central angle measures.
A quadrilateral has four angles. There is information on only three so there are infinitely many possible answers.
The four interior angles of any quadrilateral add up to 360 degrees
There are only 4 possible numbers which could be measures of the angles for the quadrilateral. Each of the infinitely many other measures, such as 36.57 degrees, could NOT be the measure.
The following are angles in a convex quadrilateral: Angle A = 80 degrees Angle B = 98 degree Angle C = 70 degrees What is the measure of the missing angle?
The sum of angles in a quadrilateral is 360 degrees.
the angle measures of a quadrilateral must equal 360 degrees so you add 80+140+55=275 then subtract from 360. the answer is 85
