Segments and angles

Symmetric Property for Segment Length and Angle Measure

AB=AB. Symmetric. If AB = CD , then CD = AB.

Vertical Angles Theorem

Vertical angles are congruent and it is easy to prove. We just use the fact that a linear pair of angles are supplementary; that is their measures add up to.

Symmetric Property of Angle Congruence

Addition Postulate If equal quantities are added to equal quantities, the sums are equal. Transitive Property If a = b and b = c, then a = c. Reflexive Property A quantity is congruent (equal) to itself. a = a Symmetric Property If a = b, then b = a.

Congruent Supplements Theorem

Congruent Complements Theorem If 2 angles are complementary to the same angle, then they are congruent to each other.

Congruent Complements Theorem

Congruent Supplements Theorem If 2 angles are supplementary to the same angle, then they are congruent to each other

Division Property

Definition. In this video lesson, we talk about the division property of equality. It is a pretty simple property. It states that if you divide one side of an equation by a number, you also must divide the other side by the same number so that your equation stays the same

Right Angle Congruence Theorem

Hypotenuse-Leg (HL) Theorem. If the hypotenuse and one leg of a right triangle are equal to the hypotenuse and one leg of another right triangle, then the two right triangles are congruent. Recall that the criteria for our congruence postulates have called for three pairs of congruent parts between triangles.

Reflexive Property for Segment Length and Angle Measure

If a line segment has the same length, the line segments would be congruent. ... If we had a triangle with the same side lengths and angle measures, the triangles would be congruent. The reflexive property of congruence shows that any geometric figure is congruent to itself.

Reflexive Property of Angle Congruence

If an angle has the same angle measure, the angles would be congruent. If we had a triangle with the same side lengths and angle measures, the triangles would be congruent. The reflexive property of congruence shows that any geometric figure is congruent to itself.

Transitive Property for Segment Congruence

Image result for Transitive Property for Segment Congruence Transitive Property (for three segments or angles): If two segments (or angles) are each congruent to a third segment (or angle), then they're congruent to each other. The Transitive Property for three things is illustrated in the above figure.

Addition Postulate

In geometry, the segment addition postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.

Algebraic Properties of Equality

Properties of equalities. Two equations that have the same solution are called equivalent equations e.g. 5 +3 = 2 + 6. And this as we learned in a previous section is shown by the equality sign =. An inverse operation are two operations that undo each other e.g. addition and subtraction or multiplication and division.

Reflexive Property

Reflexive pretty much means something relating to itself. The reflexive property of equality simply states that a value is equal to itself. Further, this property states that for all real numbers, x = x. ... Real numbers include all the numbers on a number line.

Subtraction Property

Subtraction Property of Equality: States that when both sides of an equation have the same number subtracted from them, the remaining expressions are still equal. For example: If 5 = 5, then 5 - 2 = 5 - 2.

Symmetric Property

Symmetric Property of Equality. The following property: If if a = b then b = a. This is one of the equivalence properties of equality. See also. Reflexive property of equality, transitive property of equality, transitive property of inequalities.

Symmetric Property for Segment Congruence

The photos above illustrate the Reflexive, Symmetric, and Transitive Properties of Equality. You can use these properties in geometry with statements about equality and congruence. Jean is the same height as Jean.

Properties of Angle Congruence

The reflexive property of congruence is used to prove congruence of geometric figures. This property is used when a figure is congruent to itself. Angles, line segments, and geometric figures can be congruent to themselves. Congruence is when figures have the same shape and size.

Properties of Segment Congruence

The reflexive property of congruence is used to prove congruence of geometric figures. This property is used when a figure is congruent to itself. Angles, line segments, and geometric figures can be congruent to themselves. Congruence is when figures have the same shape and size.

Substitution Property

The substitution property of equality, one of the eight properties of equality, states that if x = y, then x can be substituted in for y in any equation, and y can be substituted for x in any equation.

Addition Property

There are four mathematical properties which involve addition. The properties are the commutative, associative, additive identity and distributive properties. Additive Identity Property: The sum of any number and zero is the original number. For example 5 + 0 = 5.

Transitive Property of Angle Congruence

Transitive Property (for three segments or angles): If two segments (or angles) are each congruent to a third segment (or angle), then they're congruent to each other.

Transitive Property

Transitive Property of Equality. The following property: If a = b and b = c, then a = c. One of the equivalence properties of equality. Note: This is a property of equality and inequalities. (Click here for the full version of the transitive property of inequalities.)

Linear Pair Postulate

Two angles are a linear pair if the angles are adjacent and the two unshared rays form a line. Below is an example of a linear pair: The linear pair postulate states that two angles that form a linear pair are supplementary

Transitive Property for Segment Length and Angle Measure

measure of angle < means angle =/= means ... reflexive property of equality(segment length).

Multiplication Property

there are actually four multiplication properties. The commutative, associative, multiplicative identity, and distributive properties. Commutative: When two numbers are multiplied together, the product is the same regardless of the order of the multiplicands.
