Need help with this. A B C D

Answer 1

Answer:

yes, it is a right triangle and ∡Q is the right angle

Step-by-step explanation:

if the slope of QR is the opposite reciprocal of QS then the two segments are perpendicular and form a 90° angle

slope of QR:  -3 - (-1) ÷ 2 - 0  = -2 ÷ 2 = -1

slope of QS:  -3 - (-1) ÷ 2 - 4  = -2 ÷ -2 = 1

-1 and 1 are opposite and reciprocal so m∡Q = 90°
