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. 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.

Converse Alternate Exterior Angles If two lines are cut by a transversal and the alternate exterior angles are congruent, the lines are parallel.

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.

A rhombus is a parallelogram with four congruent sides. Mathsclinic Smartprep Gr12 Eng v2. Download now. Culture Documents. Geometry Abbreviations Geometry Abbreviations. Converse Alternate Interior Angles If two parallel lines are cut by a transversal, then the alternate interior angles are congruent. If two angles of one triangle are congruent to two angles of another triangle, the triangles are similar. Corresponding parts of congruent triangles are congruent. Listed below are six postulates and the theorems that can be proven from these postulates. My Preferences My Reading List. A parallelogram is a rhombus if and only if each diagonal bisects a pair of opposite angles. List of Theorems and Postulates. Supplements of the same angle, or congruent angles, are congruent. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. Jump to Page.

User Settings. Triangle Congruence Triangle Congruence. If a parallelogram has one right angle it is a rectangle A parallelogram is a rectangle if and only if its diagonals are congruent. If two parallel lines are cut by a transversal, the interior angles on the same side of the transversal are supplementary. Triangles: If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent. A parallelogram is a rhombus if and only if the diagonals are perpendicular. If two planes intersect, then their intersection is a line Postulate 6. File File. Mate - Info.
