Same Side Interior Angles (Parallel Lines)

Front

Ex. 3 & 5 add up to 180º

Back

Complimentary Angles

Front

Two angles that add up to 90°.

Back

Vertical Angles

Front

Formed by 2 intersecting lines or segments. Always congruent.

Back

Degree Measure of a Circle

Front

The central angles of a circle add up to 360°.

Back

Pythagorean Theorem

Front

Used to find the missing side of a right triangle. "c" is always the length of the hypotenuse. a²+b²=c²

Back

Alternate Exterior Angles (Parallel Lines)

Front

Ex. 1 & 8 are congruent

Back

Isosceles Triangle

Front

Back

Degree Measure of a Triangle

Front

The inside angles of a triangle always add up to 180°.

Back

Circumference of a Circle

Front

C=2πr or C=πd

Back

Area of a Circle

Back

Equilateral Triangle

Front

A triangle in which all three sides are equal and all three interior angles are 60°.

Back

Corresponding Angles (Parallel Lines)

Front

Ex. 1 & 5 are congruent

Back

Alternate Interior Angles (Parallel Lines)

Front

Ex. 3 & 6 are congruent

Back

Triangle Inequality Theorem

Front

The sum of the 2 shortest sides of a triangle is always greater than the length of the third side.

Back

Supplementary Angles

Front

Two angles that form a line and add up to 180°.
