Geometry Chapter 2 Test Review Show All Work Write Neatly Geometry Chapter 2 Test Review Show All Work Write Neatly This document serves as a comprehensive review for your upcoming Geometry Chapter 2 test It covers key concepts formulas and problemsolving techniques Remember showing all your work is crucial for understanding and demonstrating your learning Write neatly to ensure clear communication and avoid confusion Chapter 2 Review Topics 1 Angles and Angle Relationships Types of angles Acute Angle An angle measuring less than 90 degrees Right Angle An angle measuring exactly 90 degrees Obtuse Angle An angle measuring more than 90 degrees but less than 180 degrees Straight Angle An angle measuring exactly 180 degrees Reflex Angle An angle measuring more than 180 degrees but less than 360 degrees Angle Pairs Complementary Angles Two angles whose measures add up to 90 degrees Supplementary Angles Two angles whose measures add up to 180 degrees Vertical Angles Two nonadjacent angles formed by the intersection of two lines Vertical angles are always congruent Linear Pair Two adjacent angles that form a straight angle Linear pairs are always supplementary Angle Properties Angle Addition Postulate If point B lies in the interior of angle AOC then the measure of angle AOB plus the measure of angle BOC equals the measure of angle AOC Angle Subtraction Property If point B lies in the interior of angle AOC then the measure of angle AOC minus the measure of angle AOB equals the measure of angle BOC 2 Parallel and Perpendicular Lines Parallel Lines Lines in the same plane that never intersect They have the same slope Perpendicular Lines Lines that intersect at a right angle Their slopes are negative 2 reciprocals of each other Transversal A line that intersects two or more other lines Corresponding Angles Angles that occupy the same relative position when a transversal intersects two lines Corresponding angles are congruent if the lines are parallel Alternate Interior Angles Angles on opposite sides of the transversal and inside the two lines Alternate interior angles are congruent if the lines are parallel Alternate Exterior Angles Angles on opposite sides of the transversal and outside the two lines Alternate exterior angles are congruent if the lines are parallel SameSide Interior Angles Angles on the same side of the transversal and inside the two lines Sameside interior angles are supplementary if the lines are parallel SameSide Exterior Angles Angles on the same side of the transversal and outside the two lines Sameside exterior angles are supplementary if the lines are parallel 3 Triangles Triangle Classification Scalene Triangle A triangle with no congruent sides Isosceles Triangle A triangle with at least two congruent sides Equilateral Triangle A triangle with all three sides congruent Right Triangle A triangle with one right angle Acute Triangle A triangle with all angles acute Obtuse Triangle A triangle with one obtuse angle Triangle Properties Triangle Angle Sum Theorem The sum of the interior angles of a triangle is always 180 degrees Exterior Angle Theorem The measure of an exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles Triangle Inequality Theorem The sum of the lengths of any two sides of a triangle must be greater than the length of the third side SideAngleSide SAS Congruence Postulate If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle then the triangles are congruent AngleSideAngle ASA Congruence Postulate If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle then the triangles are congruent SideSideSide SSS Congruence Postulate If three sides of one triangle are congruent to three sides of another triangle then the triangles are congruent 3 4 Polygons Polygon Definition A closed figure formed by three or more line segments Polygon Properties Regular Polygon A polygon with all sides and all angles congruent Convex Polygon A polygon where all interior angles are less than 180 degrees Concave Polygon A polygon where at least one interior angle is greater than 180 degrees Polygon Interior Angle Sum Theorem The sum of the measures of the interior angles of an n sided polygon is n2 180 degrees Polygon Exterior Angle Sum Theorem The sum of the measures of the exterior angles of any polygon is 360 degrees 5 Quadrilaterals Quadrilateral Types Parallelogram A quadrilateral with two pairs of parallel sides Rectangle A parallelogram with four right angles Rhombus A parallelogram with four congruent sides Square A rectangle with four congruent sides Trapezoid A quadrilateral with exactly one pair of parallel sides Kite A quadrilateral with two pairs of adjacent congruent sides Quadrilateral Properties Opposite sides of a parallelogram are congruent Opposite angles of a parallelogram are congruent Consecutive angles of a parallelogram are supplementary Diagonals of a parallelogram bisect each other Diagonals of a rectangle are congruent Diagonals of a rhombus are perpendicular bisectors of each other Diagonals of a square are congruent and perpendicular bisectors of each other Practice Problems 1 Angles and Angle Relationships Find the
