## FAQs on Lines and Angle Class 6 Worksheet Maths

 1. What are lines and angles?
Ans. Lines are straight, infinite, and one-dimensional figures that have no thickness or width. Angles, on the other hand, are formed when two lines or line segments meet at a common point called the vertex.
 2. How are lines classified based on their positions?
Ans. Lines can be classified as intersecting, parallel, or perpendicular based on their positions. Intersecting lines meet or cross each other at a point. Parallel lines never meet and are always equidistant from each other. Perpendicular lines intersect at a right angle, forming 90-degree angles.
 3. What are the types of angles?
Ans. There are various types of angles, including acute angles (less than 90 degrees), right angles (exactly 90 degrees), obtuse angles (between 90 and 180 degrees), and straight angles (exactly 180 degrees).
 4. How can we determine if two lines are parallel?
Ans. Two lines are parallel if they never intersect each other and are always equidistant. One way to determine if two lines are parallel is by comparing their slopes. If the slopes of the lines are equal, they are parallel.
 5. How do we calculate the measure of an angle?
Ans. The measure of an angle can be calculated using a protractor. Place the center of the protractor on the vertex of the angle, align one side of the angle with the baseline of the protractor, and read the measurement where the other side of the angle intersects with the protractor scale.
