Bell-Ringer In the Middle Ages, the principal square root of a number x was estimated to be the average of the values obtained by using the two expressions: 𝑏 𝑏 √𝑎2 + 𝑏1 = a + 2𝑎 and √𝑎2 + 𝑏1 = a + 2𝑎+1 , where the number x = a2+ b. Find the square root of 26 using this method. Then, use the calculator and compare the answers. Write the conclusion in complete sentence. Answer: 26 = 25 + 1 = 52 + 1 X = 26 a=5, b=1 1 √25 + 1 = 5 + 10 = 5.1 5.1+5.095 2 1 √25 + 1= 5 + 11 = 5 + 0.095 = 5.095 = 5.10 2. Vocabulary, definitions and notes. Space - The set of all possible points; made up of infinite planes. 2 Isometry -A transformation that keeps the same size and shape of a figure but moves it to a new location Examples of transformations are: reflection, rotation, translation, glide reflection Transformation - a correspondence between two sets of points such that each point in the preimage has a unique image and that each point in the image has exactly one preimage. Preimage - the original object that is reflected Image - the reflection of the preimage SOLIDS Examples of Solids: 2. Bases are congruent and // circles 1. 3 3. 4. 5. Bases are congruent and // circles centce Axis of a cylinder is the line connecting the centers of two bases. Lateral Area: LA = Circumference x height Surface Area: SA = LA + 2(Area of the circle) Right cylinder: A cylinder whose axis is perpendicular to its bases. It is not a right cylinder. Why? 4 It is not a right cylinder because the axis is not perpendicular to the bases. A cylinder is analogous to a prism, except its bases are circular. A cylinder is not a polyhedron (just like a circle is not a polygon). Note: The word cylinder actually refers to any solid shape with two congruent bases in parallel planes (including prisms and solids with, say, clover-leaf-shaped bases). The cylinders we mean here are called circular cylinders. Volume = (Base area) x (height) ___________________________________ A polyhedron (Pl. polyhedra) is a solid region formed by the intersection of several (at least four) planes. The planes intersect in polygonal faces whose sides are called edges and whose corners are the vertices of the polyhedron. Surface Area: Total area of all of the faces of the polyhedron. Volume: A measure of how much space fits inside a solid figure, calculated in cubic units. Simple 6-faced solids: Cube, Rectangular solid, parallelepiped. Rectangular solid: A polyhedron with six rectangular faces. Adjacent faces intersect at right angles. A rectangular solid has three measurements: length, width and height. 5 Surface Area: SA= 2(LW + LH +HW) Rectangular solid Cube: A rectangular solid with six congruent square faces. A cube has twelve congruent edges and eight vertices. Volume: V = (side length)3 Surface Area: SA= 6(side length)2 Parallelepiped: A polyhedron whose six faces are parallelograms lying in pairs of parallel planes. Rectangular solids are parallelepipeds whose adjacent faces lie in perpendicular planes. height V= L x W x H width length Prism: A prism is a polyhedron two of whose faces (the bases) are congruent polygons lying in parallel planes; the other 6 faces (the lateral faces) are parallelograms that join corresponding sides on the congruent polygons. The sides that join the lateral parallelograms to each other are called lateral edges. - A prism is identified by the shape of its bases. Height: The (perpendicular) distance between the bases (or rather, the planes containing them). Pentagonal Prism Volume: V = Base Area x height Lateral Area (LA): The area of the lateral faces of a prism. Surface Area: SA = LA + 2(Base Area) Right Prism: A prism whose lateral edges are perpendicular to the planes containing the bases of the prism. Right triangular prism Lateral area (for right prism): LA = Perimeter of base x height 7 Special type of prisms: Parallelepipeds are prisms with a parallelogram base. Rectangular solids and cubes are right prisms with a rectangular (or square) base. Pyramid: A pyramid is the set of all points along segments that join a polygonal base with a vertex not in the plane of the base. -If the base is a polygon with n edges, the pyramid has n+1 faces: one base and n triangular lateral faces. -Height: The distance from the vertex to (the plane that contains) the base. (𝒃𝒂𝒔𝒆 𝒂𝒓𝒆𝒂)(𝒉𝒆𝒊𝒈𝒉𝒕) -volume: V= 𝟑 Pyramid with trapezoid base Base Regular pyramid: A pyramid with two properties: 1. The base is a regular polygon. 2. The line joining the vertex and the center of the base is perpendicular to (the plane of) the base. All lateral faces are congruent isosceles triangles. - Slant height: The length of the altitude of one of the lateral faces. The Pythagorean Theorem tells us that (apothem of base)2 + (height)2 = (slant height)2 -Lateral area: LA = (𝒃𝒂𝒔𝒆 𝒑𝒆𝒓𝒊𝒎𝒆𝒕𝒆𝒓)(𝒔𝒍𝒂𝒏𝒕 𝒉𝒆𝒊𝒈𝒉𝒕) 𝟐 - Surface area: SA= LA + Base area 8 Square Pyramid (Regular Pyramid) Tetrahedron: A regular triangular pyramid; tetrahedron has four triangular faces, four vertices, and six edges. ___________________________________________ Cone: A cone is analogous to a pyramid, except the base is a circle. Volume: V = = (𝒃𝒂𝒔𝒆 𝒂𝒓𝒆𝒂)(𝒉𝒆𝒊𝒈𝒉𝒕) 𝟑 𝝅 𝒓𝟐 𝒉 𝟑 Right cone Slant height: The length of the shortest segment from the vertex to a point on the perimeter of the circular base. The segment is perpendicular to the tangent to the circle at the point where the segment hits the circular base. Pythagorean Theorem states that (radius)2 + (height)2 = (slant height)2 = = π(radius)(slant height) 9 Sphere: A sphere is the three-dimensional equivalent of a circle: the set of all points in space equidistant from a fixed point called the center. The common distance is called the radius. -Hemisphere: Half of a sphere -Volume: V = 4π(radius)3/3 -Surface area: SA = 4π(radius)2 Sphere www.mathwareshouse.com WWW MATH RESOURCES PARENT CONTACT LOG.xlsx MONTHLY RESTROOM PASS.xlsx MEETINGS CALENDAR.xlsx NOTEBOOK CHECKING.xlsx VERIFICATION QUARTERLY GRADES.xlsx DAILY CLASS BEHAVIOR LOG.xlsx GRADING SCALES.xlsx HOMEWORK LOG.xlsx INTERIM ASSESSMENTS BBA-WINTER RECORDS.xlsx WWW.KUTTASOFTWARE.COM GRADE RECORDS PER SECTION.xlsx LESSON PLAN RESOURCES.xlsx http://www.dadeschools.net/calendars/11-12/11-12_el-sec.pdf www.edusoft.com (baldoquin, sb223266) web: sbaldoquin, sb223266 10 http://www.floridastandards.org/Standards/FLStandardSearch.aspx http://www.floridastandards.org/Standards/FLStandardSearch.aspx www.floridastandards.org https://employeeportal.dadeschools.net/default.aspx GIZMO RESOUCES MATH RESOURCES ONLINE www.keypress.com www.kutasoftware.com http://ehandbooks.dadeschools.net/policies/90/csc_sec.pdf TEXTBOOK MATH RESOURCE GIZMO RESOUCES\Math Exploration Guides\Algebra 11 STRATEGIES AND PRACTICES PROVIDE HINTS AND FEEDBACK INTERACTIV E PARTICIPATION HAVING STUDENTS TEACH WHAT THEY LEARNED TO SOMEONE ELSE BLOOM TAXONOMY (CONGNITIVE DOMAIN) 1.
