What are lines angles?
In geometry, lines and angles are the basic terms that set up the foundation for the subject. A line is defined as a row of closely spaced dots that extends infinitely in two directions. An angle is defined as a figure created by two rays that meet at a common endpoint. They are measured in degrees, using a protractor.

How do you find Z angles?
Alternate angles form a ‘Z’ shape and are sometimes called ‘Z angles’. a and b are adjacent angles. Adjacent angles add up to 180 degrees….Proof:
- The angles in the triangle add up to 180 degrees. So a + b + y = 180.
- The angles on a straight line add up to 180 degrees.
- Therefore y = 180 – x.
What is angle of triangle?
A triangle has three angles. The sum of the measures of the angles is always 180° in a triangle. We have different types of triangles. A triangle is classified by its angles and by the number of congruent sides. A triangle that has three acute angels is called an acute triangle.
How many angles are in a triangle?
three angles
The sum of the three angles of any triangle is equal to 180 degrees.
What are lines in math?
What is a line? In geometry, a line can be defined as a straight one- dimensional figure that has no thickness and extends endlessly in both directions. It is often described as the shortest distance between any two points.
What are the angle rules?
Basic Angle Rules
