PPT-3.1 Duplicating Segments and Angles

Objectives I CAN duplicate a segment using a patty paper and a straightedge I CAN duplicate an angle using a patty paper and a straightedge or a straightedge and a compass 1 Serra Discovering Geometry. Addition, Subtraction, Multiplication, and Division . Properties. Addition, Subtraction, Multiplication and Division Properties. I CAN…. Use the addition, subtraction, multiplication. and division properties. Angles are ACUTE angles Angles equal to 90 are RIGHT angles Angle are OBTUSE angles Angles equal to 180 Angles more than 180 are REFLEX angles ANGLES RULES Angles about a point add to 360 Anlges. Using a compass and straight edge. Types of Pictures. Sketch – freehand drawing of something, sketch a right triangle, not exact. Drawing . – using tools to accurately measure lengths and angles. Vocabulary. Congruent-the same measurement. Construct-to create. Straightedge-any object you can use to make a straight line. Compass-an instrument used to create circles or parts of circles. Arc-part of a circle that can be drawn with a compass. 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 . Anlges. Objective: Students will use a compass and straight edge to copy and construct segments and angles.. Types of Pictures. Sketch – freehand drawing of something, sketch a right triangle, not exact. Postulates. Postulate: a rule that is accepted without proof. Theorem: a rule that can be proved. Postulate 1 – Ruler Postulate. . The points on a line can be matched one to one with the real numbers. The real number that corresponds to a point is he coordinate of the point.. Protractor: . What do you notice? . Task One: . Look at the protractor. Write down everything that you notice about the protractor. Try and come up with at least . 10 facts. Think about . number patterns . Look for the similar Triangles. Parallel Lines and Transversal. Alternate interior angles are congruent if the lines are parallel. Corresponding angles are congruent if the lines are parallel. Could use SSI to prove lines parallel. The vertical distance from rotary table to Point B is called a true vertical depth. The inclination angle ‘I’ is the angle between vertical and the wellbore. . The direction angle ‘A’ is specified as the azimuth between the geographic north and the projection of a wellbore on a horizontal plane.. Lesson 2.5. In the diagram above, AB = CD.. Do you think that AC = BD?. Suppose that BC were 3cm. Would AC = BD?. If AB = CD, does the length of BC have any effect on whether . AC = BD?. A. C. B. D. Learning Target: . I can review properties of angles and segments in circles to determine their measure and length.. Agenda:. Do Now. Embedded Assessment Self-Assess. Circles Properties Review. Independent Practice. Made up of 2 rays joined together at a common point called a vertex.. The angle is . Circle . The set of points on a plane at a certain distance, or radius, from a single point, the center. Lines that intersect at 90.
