Answer:
P(-a, a)
Q(0, a)
Explanation:
The triangle is given as isosceles. It is also a right triangle since angle Q is a right angle. The legs of a right triangle form the right angle. Also, in an isosceles right triangle, the legs are congruent.
OQ = QP
The coordinates of point O are (0, 0) since point O is the origin.
Point Q lies on the y-axis, so its x-coordinate is 0.
Point Q has coordinates (0, a).
The length of OQ is a. The length of QP is also a.
That makes the coordinate of point P (-a, a).
Answer:
P(-a, a)
Q(0, a)
