1.2 – Use Segments and Congruence. Geometry Ms. Rinaldi. Postulate. In Geometry, a rule that is accepted without proof is called a postulate or axiom . Postulate 1 – The Ruler Postulate. Measure the length of ST to the nearest tenth of a centimeter.

ByDrill: Tues, 1/3 1. Identify CL and its relationship to triangle ABC. 2. Find the midpoint and slope of the segment that passes through ( 2, 8) and (–4, 6). OBJ: SWBAT prove and apply theorems about perpendicular bisectors.

ByALGEBRA. Find the values of x and y in the diagram. STEP 1. Find the value of y . Because KLN is equiangular, it is also equilateral and KN KL . Therefore, y = 4 . STEP 2.

BySegments and Rays. Lesson 2-2. Postulates. Definition: An assumption that needs no explanation. Examples :. Through any two points there is exactly one line. A line contains at least two points. Through any three non collinear points, there is exactly one plane.

ByWelcome Back! Collected Warm Up. Write your name What was your favorite thing you did over break? Think back on all the topics we covered this semester. What topic was most challenging? What topic was most interesting?. Tentative Schedule for End of Semester.

By6.1 Polygons. Vocabulary. Polygon: plane figure formed by three or more segments (called sides). Diagonal: segment that joins 2 non-consecutive vertices . Classifying Polynomials. Example 1 . Is the figure a polygon? Explain your reasoning. . Quadrilaterals .

ByDistance and Midpoints. Geometry Ms. Hough 1-3. Distance on a Number Line. Take the absolute value of the distance between the two points. PQ = │b-a│ or │a - b│ CD = │-5 - 1│ = │-6 │. P. Q. a. b. C. D. -8 -7 -6 -5 -4 -3 -2 -1 0 1 2.

BySecants and Tangents. A secant to a circle is a line that intersects the circle at two points. Secants and Tangents. A tangent is a line in the plane of the circle that intersects the circle at exactly one point. This point is the point of tangency. Tangent Theorem.

ByLesson 1.5. Division of Segments and Angles. Segment Bisector. A point (or a segment ray, or line) that divides a segment into two congruent segments bisects the segment. The bisection point is called the midpoint of the segment. Examples.

ByBisectors of Triangles. Geometry H2 (Holt 5-2) K. Santos. Concurrent & Point of Concurrency. When 3 or more lines intersect at one point, then the lines are said to be concurren t. Point of concurrency is the point where they intersect. Circumcenter of a Triangle.

ByBisectors of Triangles. Geometry (Holt 5-2) K. Santos. Concurrent & Point of Concurrency. When 3 or more lines intersect at one point, then the lines are said to be concurren t. Point of concurrency is the point where they intersect. Circumcenter of a Triangle.

ByPlease begin working on the warm up. Please add to your notes:. Vertical angles – angles across the vertex from each other. They do not share a side – only the vertex. They are congruent. Adjacent Angles – are NEXT to each other.

ByChapter 10 Section 1 – Use properties of tangents. Definitions. Circle – set of all points that are equidistant from a given point Radius – segment whose endpoints are the center of a circle and any point on the circle Chord – segment whose endpoints are on the circle

BySec 1.2 Measuring and Constructing Segments. Definitions: Coordinate Distance Length Congruent Segments Construction Between Midpoint Bisect Segment Bisector. Postulates. Segment Addition: If B is between A and C then AB +BC = AC

By1-2: Measuring & Constructing Segments. RULER POSTULATE. The points on a line can be put into a one-to-one correspondence with the real numbers. Those points are called coordinates . TERMS.

ByTrapezoid Coordinate Proofs. Prove ABCD is an isosceles trapezoid A (-18,-1), B (-6,8), C (18, 1), D (-18, -26). Parallel lines have equal slopes. A trapezoid is a quad with exactly one pair of opp. sides parallel. is a trapezoid. BC= AD= .

ByMeasuring Segments. Postulate 1-5 Ruler Postulate The points of a line can be put into one-to-one correspondence with the real numbers so that the distance between any two points is the absolute value of the difference of the corresponding numbers. Postulate 1-6 Segment Addition Postulate.

ByDefined Terms and Postulates. April 3, 2008. Defined terms. Yesterday, we talked about undefined terms. Today, we will focus on defined terms (which are based on the undefined terms from yesterday). More about space and points.

By6-2: Properties of Parallelograms. What is a Parallelogram?. Symbol for parallelogram:. ___________ of parallelograms can serve as ____________. So you then can use the following angles:. Diagonals. transversals. AIA. SSI. AEA. SSE. Corr.

ByGeometry. 1.2 Linear Measure. Line segment – part of a line with two endpoints and all points between them __ The measure of AB is always written as AB.
