What is the one thing EVERY quadrilateral has in common?
They all have FOUR sides.
100
A ________________ is an exact location in space.
What is a point.
100
True or False? ALL triangles are exactly the same.
False
200
A ________________ has nine sides.
What is a nonagon.
200
An angle with a measure of less than 90 degrees is what type of angle?
What is an acute angle.
200
This quadrilateral has only ONE pair of parallel lines.
What is a trapezoid.
200
A ______________ has one endpoint and extends FOREVER in one direction.
What is a ray.
200
Define the term "isosceles triangle."
These triangles have two equal sides.
300
True or False? The number of sides a polygon has is the same as the number of vertices the figure has. (Example: A square has four sides and four vertices.)
True
300
What is the measure of a straight angle?
What is 180 degrees
300
This four sided figure has opposite sides that are parallel and equal in length.
What is a parallelogram.
300
A _________________ is a part of a line. It has TWO endpoints.
What is a line segment.
300
A scalene triangle has ____________ equal sides.
What is zero or none.
400
Identify one reason a circle is NOT considered a polygon.
A circle is NOT made up of line segments.
400
What is the name of the common endpoint where two rays meet?
What is a vertex.
400
A ____________________ has four equal sides, but does NOT have four 90 degree angles.
What is a rhombus.
400
Define the term parallel lines.
Parallel lines NEVER cross.
400
Calculate the missing angle in the following triangle: 37 degrees, 52 degrees, _____________.
What is 91 degrees.
500
What are the characteristics of a regular polygon? (Group must name TWO out of THREE)
-Closed figure
- Made of line segments
- Equal sides and angles
500
Describe how you know which row of numbers to use on a protractor when measuring an angle.
You must know the difference between acute and obtuse angles.
500
Compare and contrast a square to a rectangle.
Squares - four 90 degree angles / four equal sides
Rectangles - four 90 degree angles / two pairs of equal sides
BOTH have FOUR sides
500
Are intersecting lines ALWAYS perpendicular? Explain.
No, perpendicular means the lines form 90 degree angles when they cross. Intersecting are simply lines that cross at some point. They do not have to form a right angle.
500
Is it possible to have more than one obtuse angle in a triangle? Explain.
No, because the sum of all three angles in a triangle is 180 degrees. Therefore, only one angle could be greater than 90 degrees.
