When you go into yoga you expect a good workout. Yoga helps improve balance, strength, and flexibility. You never really think about how many angles from geometry you make with your body. I guess math is also a good workout.

Now that you have your workout space set up it is time to start working out. In yoga the postures that you place your body into are actual called asanas. With your mind focused on geometry you start noticing other familiar terms.

You walk into a yoga class, two pieces of equipment you are asked to grab are a mat and strap. You will notice some familiar things about these two simple yoga objects. You think back to geometry class.

The yoga mat you are going to use has four right angles and four parallel lines.

Parallel lines  Two lines are parallel if they lie in the same plane and do not intersect. The symbol || means “is parallel to.”
Right angle A right angle is an angle whose measure is 90.
Straight angle A straight angle is an angle whose measure is 180.
Acute angle An acute angle is an angle whose measure is between 0 and 90.
Perpendicular lines Perpendicular lines are lines that intersect and form right angles. The symbol

⊥

⊥

up tack means “is perpendicular to.”
Vertical angles  Vertical angles are two angles whose sides form two pairs of opposite rays.
Supplementary angles Two angles are supplementary if the sum of their measures is 180.

Angle bisector An angle bisector is a ray that divides an angle into two congruent angles.
Congruent angles  Congruent angles are angles that have the same measure.
Linear pair  A linear pair is a pair of adjacent angles whose noncommon sides are opposite rays.
Alternate interior (exterior) angles Alternate interior (exterior) angles are nonadjacent interior (exterior) angles that lie on opposite sides of the transversal.
