PPT-Right Angles An angle is where 2 lines meet when creating a shape

A right angle A right angle is the corner of a square or rectangle Angles are measured in degrees 90º in a right angle We use these right angles to describe turns One turn Two turns. What is p?. A quad is a square. What is the conclusion?. It has 4 right angles. What is the converse?. If a quadrilateral has 4 right angles, then it is a square.. What is the inverse?. If a quad is not a square, then it does not have 4 right angles. Recognising different types of angles. What type of angle is this?. Right angle. What type of angle is this?. acute. What type of angle is this?. obtuse. What type of angle is this?. acute. What type of angle is this?. Objectives. State the triangle angle sum theorem and solve for an unknown angle in a triangle. Classify triangles based on measures of angles as well sides. State the triangle exterior angle theorem and solve for an unknown exterior angle of a triangle. 8.G.5. Essential Question. ?. What can you conclude about the angles formed by parallel lines that are cut by a transversal?. Common Core Standard. :. 8.G ─Understand . congruence and similarity using physical models, transparencies, or geometry software.. Parallel and Perpendicular Lines. Perpendicular lines. are two lines that intersect to form a 90º. . angle. . Parallel and Perpendicular Lines. Parallel lines. are two lines that, if extended indefinitely, would never cross or touch. Geometry Unit 4. Angles of A Triangle. Content Objective. : Students will be able to identify the properties and classifications of specific triangles, using them to solve problems.. Language Objective. 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 . Unit 3: This unit Introduces Transversals, and angles based on transversals, including corresponding angles, Same Side Interior Angles, Alternate Exterior and Alternate Interior Angles, and the unique properties of Perpendicular Transversals. . 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.. Section 3.1 – Lines and Angles. I CAN identify relationships between figures in space.. I CAN identify angles formed by two lines and a transversal.. Key Vocabulary:. Parallel Lines. Skew Lines. Parallel Planes. 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. Exemplification Work out the size of each angle. Diagrams are not drawn accurately. 72.5° 162 ° 206° D E F O °   °   Form and solve an equation and find the value of .   _______   FOE Angles of Triangles Objectives Find angle measures in triangles.
