Question

The y axis is a line of symmetry for a triangle. The coordinates of two of its vertices are (-3, 2) and (0,5)

A. What are the coordinates of the third vertex?
B. What is the area of the triangle?

Answer 1

A. (3,2)

B. 4.5

Explanation:

A. since its symmetrical over the y axis both bottom points will be the same except the x will be opposite

B. take (0,5) and minus (-3, 2) which will get you (3,3) do 3x3divided by 2 which gets you4.5
