Tuesday, January 27th Computer Lab Assignment

Welcome to your first blog-based assignment! You should have a copy of the LearnZillion note template. Follow the link below to LearnZillion. You have two videos to watch and you should take notes on the template. You do not need to log in; you only need to type the QUICK CODE at the top of the page. Once you complete one side, turn the page over and enter the second QUICK CODE to launch the next video.

Here are your goals for the lesson:
I can define the word "cross section".
I can identify the 2D figure which is made when a 3D figure is sliced.

These will be your learning targets for Wednesday's lesson, so keep your note templates until then.

You're all set! Click HERE to get started. 

Geometry

This week we kicked off our study of geometry with a project using spaghetti. The students made 8 lengths of pasta and tried to try to construct different triangles. We then derived the rules of triangles.

Since vocabulary is a huge part of geometry, I am attaching a list of the "Words to Know". The list is also in the composition book.

Geometry Words to Know

Point	An exact location in space
Line	A series of points that extend in both directions without end
Ray	A series of points that extend in one direction and has one endpoint
Segment	A part of a line with two endpoints
Plane	A flat surface
Intersecting lines	Lines that have one point in common
Parallel lines	Lines in the same plane that never intersect
Perpendicular lines	Lines that intersect at a 90° angle
Skew lines	Lines that are on different planes so they can never intersect
Angle	Two rays with a common endpoint
Vertex	The point of intersection of two sides of an angle or figure
Acute angle	An angle that measures less than 90°
Right angle	An angle that measures exactly 90°
Obtuse angle	An angle that measures between 90° and 180°
Straight angle	An angle that measures exactly180°
Complementary angles	Two angles that add up to 90°
Supplementary angles	Two angles that add up to 180°
Adjacent angles	Two angles that share a vertex
Vertical angles	Angles formed by two intersecting lines that are opposite each other
Congruent angles	Angles with equal angle measures
Congruent sides	Sides that have the same measure
Scalene	No congruent sides (triangles)
Isosceles	Two congruent sides (triangle)
Equilateral	All sides congruent (triangles)
Polygon	A closed figure made of only line segments
Regular polygon	A polygon with all sides and angles congruent
Irregular polygon	A polygon with sides that are not all congruent
Circle	A set of points on a plane that are all equidistant from one point
Radius	The distance from the center of the circle to the outside
Diameter	The distance from one side of a circle to the other that goes through the cent
Arc	A part of the circle (the outside)
Semicircle	Half of a circle
Compass	A tool used to draw circles
Midpoint	A point the divides a line segment into two equal lengths
Segment bisector	A line, segment, or ray that does through the midpoint of a segment
Area	The amount of space inside a 2d figure
Perimeter	The distance around a polygon
Circumference	The distance around a circle
Volume	The amount of space inside a 3d figure
