Points/Lines/Segments/rays/angles
This names a location in space.
point
2 times, radius
What is a quadrilateral? Be SPECIFIC. Will choose the best answer if not answered 100 percent with first group.
What are the four types of triangles?
Right, Scalene, isosceles, and equilateral
What are the two axes on a coordinate grid? And which way do they go?
x axis and y axis
right and up
Draw a ray, line segment, and line.
Any line segment with both endpoints on a circle (will not go through the center.
What is a parallelogram?
Draw a octagon
see whiteboard
The point where the x and y axes intersect is called the what? what is it represented by?
Origin and it is represented by the number 0
When two rays meet at a common point it forms a what?
vertext
What is a perpendicular line?
Intersecting lines or lines that cross ad form FOUR right angles.
What is the difference between a square and a rhombus?
They both are quads with two set of parallel sides of equal length, BUT a rhombus does not have four right angles.
A polygon that has ____ angles is a ...
nine
five
four
nonagon
pentagon
quadrilateral
(5,7) is called a white? which way do you go first to plot?
Tell me all the types of angles and their measurements.
Right- 90
Acute- less than 90
obtuse- great than 90 less than 180
straight-180
Draw the symbols for both perpendicular lines and parallel lines on the whiteboard.
teaher will check
What quad is not considered a parallelogram? and describe that shape
Trapezoid
it has exactly one pair of parallel sides
Describe a polygon
Shape that is closed with straight sides.
Which ways do each axis go? (not right or up but....)
and be specific which one is which
horizontal and vertical
x is horizontal and y is vertical
When we name an angle, where does the vertex have to be?
in the middle. Example <ABC B is the vertext
Any line segment that passes through the center of a circle and has both endpoints on the circle is the what?
diameter
What do we use to show when sides of a shape are the same length?
Can a rectangle be a square? Why?
tick marks
no it cannot be a square because it does not have all sides the same length
Describe the four types of triangles
Right- have right angles
isosceles- two sides of the same length
equilateral- all sides the same length
scalene-no sides the same length
Draw a coordinate grid with both axis having 5 coordinated. Then plot :
A (3,0)
B (2,5)
C (5,2)
