Why are alternate interior angles and altenate exterior angles both called alternate?
because they do'nt lie on the same side of the trasversal!!
What are the two interior angles called that are not adjacent to an exterior angle?
In a polygon there are no such angles.
If 2 parallel lines are cut by a transversal alternate interior angles are what?
When 2 parallel lines are cut by a transversal some of the pairs of angles which are formed are called alternate angles whereas other pairs are called interior angles.
How do you prove that 2 lines are parallel?
To actually prove this, you need a line that cuts across the two parallel lines. This is called a transversal. That creates 8 angles (this would be a lot easier to explain with a diagram). If the lines are parallel, then one of these statements will be true: (i) corresponding angles will be equal (ii) alternate interior angles will be equal (iii) alternate exterior angles will be equal (iv)the interior angles on the same side of the transversal will be supplementary, i.e. add up to 180° Of course, this only applies in Euclidean Geometry. There are branches of Geometry, called Non-Euclidean Geometry which is based around different postulates but that's another story and it is exciting.
What is the definition of consecutive exterior angles?
pairs of angles on one side of the transversal but outside the two lines are called consecutive exterior angles .
Why are alternate interior angles and altenate exterior angles both called alternate?
because they do'nt lie on the same side of the trasversal!!
What is Two angles with a common side but not common interior points?
Those angles are called Alternate Exterior Angles. When two lines are crossed by another line (which is called the Transversal), the pairs of angles on opposite sides of the transversal but outside the two lines are called Alternate Exterior Angles.
What are angles that form linear pairs with interior angles called?
exterior angles
What are the two interior angles called that are not adjacent to an exterior angle?
In a polygon there are no such angles.
If 2 parallel lines are cut by a transversal alternate interior angles are what?
When 2 parallel lines are cut by a transversal some of the pairs of angles which are formed are called alternate angles whereas other pairs are called interior angles.
What are z and c and f and x angles called?
z: alternate interior angles c: consecutive interior angles f: corresponding angles x: vertically opposite angles
What is the Sum of an exterior angle of a triangle and its adjacent interior angle is called?
They are called supplementary angles.
If alternate interior angles are congruent than lines are parallel what is it called?
It is the transversal line that cuts through parallel lines creating alternate equal angles.
What is an alternate interior angle?
Two lines are crossed by one another line called the transversal. The pairs of angles on opposite sides of the transversal but inside the two lines are called alternative interior angles.
When two coplanar lines are cut by transversal the angles between the two lines on opposite sides of the transversal are called what?
Alternate Interior Angles
What is the name of polygon that has 40 degrees exterior angle and have an interior angles has 1260 degrees?
It has 9 sides and is called a nonagon
What are two angles called when they're in a plane share a vertex and a side bt no common interior points?
A possibility is the interior and exterior vertex angles add up to 180 degrees which are supplementary angles * * * * * On the basis of the information given in the question, they are simply adjacent angles.
