Angles are formed by measuring a line from the centre of a circle to the edge of the circle marked in degrees, minutes and seconds. A protractor and ruler are commonly used to measure and draw angles.
A complete circle is 360 degrees.
A half circle is 180 degrees.
A quarter circle is 90 degrees.
A right-angle triangle has one corner with an angle of 90 degrees. The two other angles are both 45 degrees. 90 + 45 + 45 = 180 degrees (half a circle).
The right-angle triangle is actually half of a square. If two such triangles were to be joined together to form a square, all angles will add up to 360 degrees.
90 + 45 + 45 =180 x 2 = 360 degrees.

Verticle angles.
What angles are formed by lines that are perpendicular?
90 degree angles.
What kind of angles are pairs of opposite and congruent angles formed by intersecting lines?
Angles that are pairs of opposite and congruent lines formed by intersecting lines are intersections
How many angles are formed by an angle bisector?
4 angles are formed

two adjacent angles formed by two intersecting tines are
What are the angles formed when parallel lines are cut through by transversal line?
The angles formed are supplementary, equal corresponding and equal alternate angles
Angles are two nonadjacent angles formed by intersecting lines are what?
Verticle angles.
What are two nonadjacent angles formed by two intersecting angles?
Verticle angles.
What angles are formed by lines that are perpendicular?
90 degree angles.
How do you find coterminal angles?
Coterminal angles are angles that are formed at the same vertex.
What is the opposite angles formed by two intersecting lines?
Opposite angles are equivalent when formed by two intersecting lines
If two angles are not vertical then they are not nonadjacent angles formed by two intersecting lines?
False. The angles can be formed by two skew lines intersecting a third line.
What is the opposite angles formed by the intersection of two lines?
They are equal opposite vertical angles and if the lines are perpendicular to each other then 90 degree angles are formed.
What kind of angles are pairs of opposite and congruent angles formed by intersecting lines?
Angles that are pairs of opposite and congruent lines formed by intersecting lines are intersections
Are angles formed by a base and the legs?
Not only. They can be formed by the legs.
