Question

Which of the following describes an angle with a vertex at Y?

A. ZYX
B. XYZ
C. ZXY
D. XZY

Answer 1

The correct options are A and B.

Explanation:

The angles are represented by three capital letters like: ABC or DEF. In these names middle letter represent the vertex of the angle.

The order or first and last letter does effect the angle. It means

`ABC=CBA`

We have to find the angle with a vertex at Y. It means the middle letter must be Y.

In option A and B the middle letter is Y, therefore both options are correct.

In option C and D the middle letter is not Y, therefore both options are incorrect.
