Geometry postulates and theorems list with pictures

If equal quantities are added to equal quantities, the sums are equal. If equal quantities are subtracted from equal quantities, the differences are equal.

A postulate is a statement that is assumed true without proof. A theorem is a true statement that can be proven. Listed below are six postulates and the theorems that can be proven from these postulates. Example 1: State the postulate or theorem you would use to justify the statement made about each figure. Through any three noncollinear points, there is exactly one plane Postulate 4.

A postulate is a statement that is assumed true without proof. A theorem is a true statement that can be proven. Listed below are six postulates and the theorems that can be proven from these postulates. Example 1: State the postulate or theorem you would use to justify the statement made about each figure. Through any three noncollinear points, there is exactly one plane Postulate 4. If two points lie in a plane, then the line joining them lies in that plane Postulate 5. If two planes intersect, then their intersection is a line Postulate 6. If two lines intersect, then exactly one plane contains both lines Theorem 3. If a point lies outside a line, then exactly one plane contains both the line and the point Theorem 2. If two lines intersect, then they intersect in exactly one point Theorem 1.

Geometry is a very organized and logical subject. So before moving onto the geometry theorems list, let us discuss these to aid in geometry postulates and theorems list. Geometry Postulates are something that can not be argued. Example: - For 2 points only 1 line may exist. It is the postulate as it the only way it can happen. Or when 2 lines intersect a point is formed. Unlike Postulates, Geometry Theorems must be proven. Let us go through all of them to fully understand the geometry theorems list.

Complements of the same angle, or congruent angles, are Congruent Complements congruent. If two parallel lines are cut by a transversal, the interior angles on the same side of the transversal are supplementary.

Side-Angle-Side SAS If two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle, the Congruence triangles are congruent. If two angles of a triangle are congruent, the sides opposite these angles are congruent.
