Question

Three angles of a quadrilateral are 50°, 80° and 170°. Find out if it is a convex or concave quadrilater
​

Answer 1

Answer:

it is a convex quadrilateral

Step-by-step explanation:

the three angles of a quadrilateral are 50°,80° and 170°

let forth angle of quadrilateral be x

The sum of all the angles of a quadrilateral =360°

50°+80°+170°+x=360°

300°+x=360°

x=360°-300°

x= 60°

since all the interior angles of the quadrilateral are less than 180°

then it is convex quadrilateral
