In this angles in circles worksheet, 10th graders solve 10 different problems that include tangents and chords and intersecting chords. First, they find x when given 2 intersecting chords. Then, students determine x given the diameter that is perpendicular to a chord. They also determine the measure in degrees of the arc of the outside edge of the part of circle.
Learners explore Venn Diagrams. In this secondary math lesson, students consider Venn diagrams as a problem solving tool for narrowing down a list of suspects. Learners are provided with information regarding possible suspects and they create Venn diagrams to organize the information and narrow their suspect search.
Students are introduced to the basic trigonometric identities. Using a diagram, they discover why the parts of the unit circle as named as they are and use equations to finalize the Pythagorean trigonometric identities. They also review basic algrebra terminology that could be useful in the present.
Eleventh graders explore the three basic trigonometric functions. In this trigonometry/Algebra II lesson, 11th graders use GeoGebra and the unit circle to define the ratios of sides is a right triangles as they examine the full domain for the function. Students switch from measuring angles in degrees to radians.
In this equations of circles worksheet, 10th graders solve 10 different problems that include graphing different circles. First, they convert the equations into center-radius form given the coordinates of the center of the circle and its radius. Then, students state the equation of a circle in standard form that has a given center and radius. They also write a center-radius equation for each graph of a circle found on the bottom of the sheet.
In this geometry worksheet, learners find the sum of the perimeters of three small circles. These small circles are tangent to each other and to a larger circle. The centers of the small circles have their centers on the diameter of the larger circle. A sketch is provided.
In this circles worksheet, 10th graders solve 10 different problems that include determining the chords, secants, and tangents of circles shown. First, they determine 4 different line segments given a circle with secants and chords with dimensions. Then, students determine a line segment in another circle given the diameter perpendicular to a chord.
Investigate the properties of a Unit Circle, wahoo! Your class will memorize the basic identities of sine, cosine, and tangent. Then those smart cookies can investigate the negative of an angle measure using sine and cosine. Included are a series of critical thinking questions and vocabulary list is included.
Eighth graders study the important definitions that are include in the lesson including; polygons, perpendicular, bisector, chord, secant, and tangent. In guided practice they make segments with rulers and protractors, make angles with compasses and straightedges, and make bisectors with a compass. Finally, they apply the strategies when completing independent student practice.
For this circles and ellipses worksheet, students solve and complete 5 different types of problems. First, they write each equation in standard form. Then, students graph and label Write the equation of the ellipse whose center is the center of the circle all of the important points as listed. They also write the equation of the ellipse whose center is the center of the circle of the given equation.
