Polypro . Presentation by: Kerry Daugherty, Alison Divens, Ryan Warfel, Jennifer Watters, Ashlie Hill, Matt Winner, Lindsey Camarata, Amanda Hauf . Polyhedra. Polyhedra are three-dimensional solids which consist of a collection of polygons, usually joined at their polyhedron edges.

ByGeometry Mini-Lesson. Tony is drawing a regular polygon. He has drawn two of the sides with an interior angle of 120°, as shown below. How many sides will the regular polygon have when Tony completes his drawing?. 6 7 8 9 .

ByFinding the Measure of Angles in Polygons. In a regular polygon, all the angles and sides are the same size. To find the measure of a single angle: Divide the Sum by the Number of Sides. For example:

ByHow to draw a perfect star. By Ellie Hughes and Scarlett Griffin. Draw a regular pentagon. To figure out the angle size, the equation is 3 X 180 divided by 5 (number of sides) = 108 degrees this is because you can fit 3 triangles in a pentagon and there is 180° in a triangle.

ByPART 3 Angle Relationships. Angle Relationships. Lesson Objectives - Students will: Discover angle properties such as: Complementary, Supplementary, vertically opposite, Corresponding, Alternate, interior. Investigate properties of triangles and quadrilaterals.

BySymmetry: A Visual Presentation. A PowerPoint Presentation created by Mrs. Gamache using the collection of web pages created by the Adrian Bruce and students of 6B http://www.adrianbruce.com. Line Symmetry. Shape has line symmetry when one half of it is the mirror image of the other half.

BySymmetry: A Visual Presentation. Line Symmetry. Shape has line symmetry when one half of it is the mirror image of the other half. Symmetry can have vertical, horizontal or diagonal line symmetry. Is a butterfly symmetrical?. Line Symmetry exists in nature but you may not have noticed.

ByBellwork : REVIEW. Happy Hal offered Joshua a job. Hal said that Joshua would make $500 commission for every $7500 in sales. Jolly Joe offered Joshua a job making $300 commission for every $5000 in sales. Which offered Joshua the better commission rate?. Bellwork.

ByPOLYGONS. A polygon is a shape enclosed by straight lines. TRIANGLE. QUADRILATERAL. sum of interior angles . sum of interior angles = 180°. = 2 x 180 ° = 360 °. PENTAGON. HEXAGON. sum of interior angles . sum of interior angles . = 4 x 180 ° = 720 °. = 3 x 180 ° = 540 °.

By11-4 Area of Regular Polygons and Composite Figures N#____ ____/____/____ Students will be able to find areas of regular polygons and composite figures. B. The regular pentagon ABCDE is inscribed in Circle F F is the center of the regular pentagon.

By10-3: Areas of Regular Polygons. Warm-Up: . The radius of a regular polygon is the distance from the center to a vertex. The apothem is the perpendicular distance from the center to a side. Find the measure of each numbered angle. a) b) .

By10-3 Areas of Regular Polygons. Definitions. Center of a regular polygon the center of the circumscribed circle. Radius of a regular polygon the distance from the center to a vertex. All radii of a figure are congruent.

By10.5 Area of Regular Polygons. Vocabulary. Areas of Regular Polygons . What You'll Learn. You will learn to find the areas of regular polygons. . 1) center 2) apothem. Areas of Regular Polygons . Every regular polygon has a ______, . center.

ByExample 1. Explain how you could find the area of the regular hexagon shown. Regular Inscribed Polygon. The diagram shows a regular polygon inscribed in a circle. Center of circle = center of the polygon Radius of circle = radius of the polygon. Regular Inscribed Polygon.

By10.3 Areas of Regular Polygons. Regular Polygons. Regular polygons:. -all sides congruent. -all angles congruent. -convex. We can center any regular polygon inside of a circle:. radius – the distance from the center to a vertex. apothem – perpendicular distance from the center to a side.

ByName______________________________ Period_________ Regular Polygons . Directions: Solve and correctly round to the nearest tenth. 1. Find the area of a regular octagon with a side length of 12 units and an apothem of 14.5 units. Show all of your work.
