Co- Interior Angle Theorem!

Linear Pair Of Angles.

Corresponding Angles!

This is a transversal.

Complementary Angle Theorem! (CAT)

Obtuse : An angle that is greater than 90 degrees but less than 180 degrees

Types of angles!

Complementary angle theorem (CAT) - When two adjacent angles add up to 90 degrees.

CAT, SAT, OAT AND SAIT.

**Angle Relationships.**

A isosceles triangle is a triangle where two sides have equal length.

A right angle is an angle of 90°, as in a corner of a square or at the intersection of two straight lines

An equilateral triangle is where all sides are the same length.

An equilateral triangle is a triangle where all sides are the same length.

Equilateral Triangle.

Can you identify what angle theorem this is?

1. Co-Interior Angle Theorem : two angles on the same side of a 'C' like shape which can be tilted. The sum of two co-interior angles added together is always 180º.

2. Alternate Angle Theorem : When two lines are crossed by another line, the pairs of angles on opposite sides of the transversal but inside the two lines are called Alternate Interior Angles.

3. Corresponding Angle Theorem : Two angles that show an F like shape. They are created when a line crosses two parallel.The angles which are the 2 obtuse angles.

Alternate Angle Theorem!

A scalene Triangle has no sides that are the same.

Her platform ( The part she passes the ball with), is an isosceles triangle, because it has two sides that are the same length. Her left leg is a right angle.

Acute : An angle that is 89 degrees or lower.

Right : An angle that is equal to 90 degrees.

Reflex : An angle that is more than 180 degrees but less than 360 degrees.

Straight : an angle that is exactly 180 degrees.

Supplementary Angle Theorem (SAT) - When two adjacent angles add up to 180 degrees.

Opposite Angle Theorem (OAT) - When two angles are not adjacent, and are on the other side of a ray.

Some Angles In Triangle ( SAIT) - When all the angles in a triangle add up to 180 degrees.

In this picture there are: opposite angles,adjacent angles, linear patterns, the corresponding angles, co-interior angles, supplementary angle theorem and alternate angle theorem
