Question

1. what are the coordinates of w? isosceles trapezoid (-a,0) o (a,0) (b,c) w z (-a,c) (a,c) (-b,c) (b,-c)

Explanation:

Step1: Analyze symmetry of isosceles trapezoid

In an isosceles trapezoid symmetric about the y - axis, points on the top - parallel side have the same y - coordinate. The y - coordinate of the point $(b,c)$ is $c$, so the y - coordinate of point $W$ is also $c$.

Step2: Analyze x - coordinate based on symmetry

Since the trapezoid is symmetric about the y - axis and the x - coordinate of the point $(b,c)$ is $b$, the x - coordinate of the corresponding point $W$ on the left - hand side will be the negative of $b$. So the x - coordinate of $W$ is $-b$.

Answer:

$(-b,c)$
