#### Adding and measuring simple angles

You can draw two intersecting lines and measure the angle between them. For example, using the Simple Angle tool, you can measure a baby’s hip. The angle is measured in degrees. To measure an angle between two non-intersecting lines, see Adding and measuring Cobb angles.

Step 1: Select the Simple Angle tool

To select the tool:

| 1. | Click the Annotate icon on the main toolbar.

| 2. | Click the Simple Angle tool on the Annotation Control Panel.

For other ways to select the tool, see Selecting an annotation tool.

Step 2: Adjust the Simple Angle tool properties (if necessary)

For an overview of annotation properties, see Setting the annotation properties.

To adjust the tool properties:

| 1. | Follow steps 1-3 of Step 2: Adjust the Distance tool properties (if necessary).

| 2. | Specify where to place the measurement. The following table describes the available options.

Option | Meaning
Start | Place the measurement at the beginning of the first line segment.
Vertex | Place the measurement between the two line segments.
End | Place the measurement at the end of the second line segment.

Step 3: Draw and measure the angle

To draw and measure an angle:

| 1. | Draw the first line segment (Start to Vertex).

| • | Drag the mouse pointer across the image.

| • | Release the mouse button.

| 2. | Click where you want to place the end of the second line segment (Vertex to End).

An angle with the measurement it represents is displayed on the image. The measurement is rounded off to the nearest integer.
