Answer 2

Drawing and Coloring an Angle

To draw an angle of 150°, follow these steps:

1. Start by drawing a straight line segment. 2. Place the protractor on the line segment, aligning the baseline of the protractor with the line segment. 3. Locate the 0° mark on the protractor and mark it as point A. 4. Count 150° clockwise from point A and mark it as point B. 5. Draw a line segment from point A to point B.

To color the additional part of the angle, you can use a strip or a small section adjacent to the angle. Color it in a different shade or pattern to distinguish it from the main angle.

Understanding Angles

An angle is formed when two rays share a common endpoint, called the vertex. In this case, the rays are the line segments AB and AC, where A is the vertex.

The angle formed by line segments AB and AC can be considered as two separate angles: angle BAC and angle CAB. These two angles together make up the entire angle of 150°.

Special Features of the New Angle

The new angle formed by coloring the additional part has some interesting properties:

1. It is a complementary angle to angle BAC. A complementary angle is an angle that, when added to another angle, results in a sum of 90°. In this case, angle BAC + the new angle = 90°.

2. The new angle is also a supplementary angle to angle CAB. A supplementary angle is an angle that, when added to another angle, results in a sum of 180°. In this case, angle CAB + the new angle = 180°.

Measurement of the New Angle

The measurement of the new angle can be determined by subtracting the measurement of the original angle from 180°. Since the original angle is 150°, the new angle can be calculated as follows:

180° - 150° = 30°

Therefore, the new angle contains 30°.
