# In Review Exercise 27 to 30, supply the missing coordinates for the vertices, using as few variables as possible. Isosceles △ A B C with base A C -

To determine

To find:

The missing coordinates for the vertices.

Explanation

The given figure is shown below.

From the figure, the following observations are made.

Consider the vertex C.

Here, x-coordinate is given as a.

In the C vertex, observe where it lies on y- axis.

Since, it is at 0, the vertex C has the coordinates a, 0.

Since, the vertex A lies on the left side of origin, its x-coordinate is negative of the x-coordinate of C.

The coordinates of A is a, 0
