# Q4, W1: March 29-April 2 Geometry Teacher Kristin Andreason Geometry Honors 8 March 29-April 2 Unit 6: Two-Dimensional Measurements
Standard(s) Taught

MAFS.912.G-GPE.2.7:  Use coordinates to compute perimeters of polygons and areas of triangles and rectangles, e.g., using the distance formula.

MAFS.912.G-CO.1.3:  Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto itself.

MAFS.912.G-CO.4.13:  Construct an equilateral triangle, a square, and a regular hexagon inscribed in a circle.

MAFS.912.G-CO.1.5: Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using, e.g., graph paper, tracing paper, or geometry software. Specify a sequence of transformations that will carry a given figure onto another.

Learning Targets and Learning Criteria
• use the distance formula to compute the perimeter and area given the coordinates of vertices of a polygon like triangle, square, rectangle, kite, rhombus, trapezoid, etc.
• decompose more complex figures whose vertices are given using coordinates into familiar shapes that are easier to work with.
• describe and illustrate how a rectangle, parallelogram, and trapezoid are mapped onto themselves using transformations.
• calculate the number of lines of reflection symmetry and the degree of rotational symmetry of any regular polygon.
• define inscribed polygons.
• construct an equilateral triangle, a square, a hexagon inscribed in a circle.
• explain the steps to constructing and equilateral triangle, a square, and a regular hexagon inscribed in a circle.
• draw a specific transformation when given a geometric figure and a rotation, reflection, or translation.
• predict and verify the sequence of transformations (a composition) that will map a figure onto another.
Classroom Activities

Monday/Tuesday:

1. Students will log onto the Zoom session.
2. We will use the Math Open Reference website to learn how to construct a square, triangle, and hexagon inscribed in a circle.
3. We will go to the Geogebra website and explore rotational symmetry and line symmetry,
4. Students will do IXL L.11.
5. We will review transformations and do a few problems on mapping a figure onto another one.
6. We will do some notes and practice on finding the area and perimeter on the coordinate plane.
7. Students will do IXL S.6.

Wednesday:

1. There are no Zoom sessions today.  Face to face students will participate in the Rainforest FSA/EOC Review Day!

Thursday/Friday:

1. Students will log onto the Zoom session.
2. Students will take notes on Population Density and do a few examples.
3. We will learn how to find the area of compound figures and will do some practice problems together.
4. We will do a few problems on Compound figures from the workbook (p. 167).
5. We will do Quizlet Live to review properties of Quadrilaterals.
