|
An angle with a measure of less than 90 degrees.
|
|
|
What is a right angle?
|
An angle with a measure of 90 degrees.
|
|
|
What is an obtuse angle?
|
An angle with a measure of greater than 180 degrees.
|
|
|
What is a complementary angles?
|
Two angles whose measures have a sum of 90 degrees.
|
|
|
What are a supplementary angles?
|
Two angles whose measures have a sum of 180 degrees.
|
|
|
What are verticle angles?
|
Are congruent angles formed by two intersecting lines.
|
|
|
What are interior angels?
|
Are angles that lie between the two lines that are cut by a transversal.
|
|
|
What are exterior angles?
|
Are angles that lie outside the two lines that are cut by a transversal.
|
|
|
What are alternate interior angles?
|
They are interior angles that lie on opposite sides of a transversal. If the lines are paralle, then the alternate interior angles are congruent.
|
|
|
What are alternate exterior angles?
|
They are exterior angles that lie on opposite sides of a transversal. If the lines are parallel, then the alternate exterior angles are congruent.
|
|
|
What are corresponding angles?
|
They are angles that lie on the same side of a transversal, in corresponding positions with respect to the two lines that it intersects. If the lines are parallel, then the corresponding angles are congruent.
|
|
|
What are adjacent angles?
|
They are angles that share a common side and a common vertex.
|
|
|
What is a point?
|
It is a single location or position that has no size or dimension.
|
|
|
What is a line?
|
A line is all the points on a straight path; it extends in both directions without end.
|
|
|
What is a ray?
|
A ray is all the points on a straight path; it extends in one direction from an endpoint without ending.
|
|
|
What is a segment?
|
A segment is all the points on the straight path between two endpoints, including the two endpoints.
|
|
|
What are intersecting lines?
|
Intersecting lines are lines that meet at a point.
|
|
|
What are parallel lines?
|
Parallel lines are lines in the same plane that never intersect.
|
|
|
What are perpendicular lines?
|
Perpendicular lines are lines that meet to form right angles.
|
|
|
What is transversal?
|
It is a line that intersects two or more lines in the same plane at different points.
|
|
|
What is the sum of interior angles of a polygon?
|
180degrees (n-2)
n= number of sides of the polygon. |
