Flashcards (Properties)

Front

Reflexive Property of Equality

Back

a = a

Front

Symmetric Property of Equality

Back

If a = b, then b = a

Front

Transitive Property of Equality

Back

If a = b and b = c, then a = c

Front

Substitution Property of Equality

Back

If a = b, then a may be replaced by b in any equation or expression

Front

Segment Addition Postulate

Back

If A, B, and C are collinear, then AB + BC = AC

Front

Angle Addition Postulate

Back

The sum of two adjacent angle measures will equal the angle measure of the larger angle that they form together.

Front

Complement Theorem

Back

If the noncommon sides of two adjacent angles form a right angle, they are complementary angles, adding up to 90 degrees.

Front

Vertical Angles Theorem

Back

When two lines intersect, the angles formed opposite each other at a vertex are congruent.

Front

Right Angles Theorems - Perpendicular Lines

Back

Perpendicular lines intersect to form four right angles.

Front

Right Angles Theorems - Congruent Right Angles

Back

All right angles are congruent.
