What is the name of the triangle that doesn't have any sides that are equal?
Scalene
100
What does the word "quadrilateral" mean?
Quadrilateral just means a four sided shape with straight sides.
100
What does the word congruent mean?
Congruent means equal in size and shape. Congruent sides and segments have the same length, congruent angles have the same number of degrees, and congruent figures and equivalent sides, faces and angles.
100
The angle that is called a right angle is how many degrees?
A right angle is always 90 Degrees.
100
What does line of symmetry mean?
If you fold a shape in half and it has a line of symmetry you will he a reflection (one half is the reflection of the other half)...it is the imaginary line where you could fold the image and have both halves match exactly.
200
If a triangle has two angles that are 60 degrees, what is the remaining angle going to be?
60 Degrees
200
Another name for a square is?
A rhombus
200
What does similar shape mean?
A similar shape means that shape A is similar to shape B in that shape A is a circle and shape B is a circle. Similar shapes have a different size, but are equal in proportion and ratio.
200
What is the definition of an obtuse angle?
An obtuse angle is more than 90 degrees, but less than 180 degrees.
200
What does parallel mean?
Parallel is when two lines lay in the same plane but do not intersect, and will maintain a constant distance from one another.
300
If I am given one angle in a scalene triangle how do I find the other two angles?
You know that two angles in a scalene triangle are the same, so if it's one of the bottom two angles than the other angle will be the same. After this step you subtract the two angles on the bottom from 180 degrees.
300
What is the total of degrees in a quadrilateral?
360
300
Congruent shapes are similar. True or False?
True
300
What is an acute angle?
An acute angle is less than 90 degrees but greater than 0 degrees.
300
How many lines of symmetry does a square have?
4 lines.
400
Define "Equilateral Triangle"
Three equal sides, three equal angles that are always 60°.
400
What is the definition of a trapezoid?
A trapezoid is a quadrilateral with only one pair of parallel sides.
400
Similar shapes are congruent? True or False?
False. They do not always have the same lengths or angles.
400
What happens when line AB is perpendicular to line CD?
The two lines intersect and create a 90 degree angle.

In class,we used a compass to:_____________, _______________,________________.
1. bisect angles, draw perpendicular lines and draw parallel lines.
500
What if I am given a triangle: (see the example Ms.Laurie draws on the board) and how do I solve the interior angle.
subtract from 180 degrees

Name 4 quadrilaterals (you have 15 seconds)
Square, Rhombus, rectangle, trapezoid
500
If you have two rectangles each with a perimeter of 30 squared cms, will their areas be equal as well? You have 1 min to explain!
No...for example you could have rectangle A that is L=7, W=8 (Perimeter =7+7+8+8=30cm and Area=7x8=56 squared cm) and you rectangle B that is L=12, W=3 (Perimeter=12+12+3+3=30cm and Area=3x12=36 squared cm).
500
What does it mean to "bisect" an angle? Bisect an angle on the board using the protractor provided.
Bisect means to separate an angle equally into two halves (they are both the same degrees).
500
This shape can have 3, 2 or no equal sides.
Trapezoid.
