Is quadrilateral RSTV a rectangle?
(1) The measure of ∠RST is 90o
(2) The measure of ∠TVR is 90o
(1) The measure of ∠RST is 90o
(2) The measure of ∠TVR is 90o
My first guess would be E.
90º+90º=180, sum af angles of quadrilateral is 360;
leaves 180º possible 90º+90º(which would mean it's a rectangle), 100º+80º (which would mean it's not);
OA?
