1.What is concave polygon? 2.What is convex polygon?
1. Concave polygons are polygons that have interior angles that are over 180 degrees. 2.Convex polygons are polygons that have interior angles under 180 degrees.
100
What is a polygon with four equal sides?
A square
100
What are parallel lines?
Parallel lines are lines that will never touch.
100
What is an angle? What are some kinds of angles? How could you use one of the angles in the real world?
An angle is where two lines meet eachother. Some kinds of angles are Complementary and supplementary, adjacent, vertical, interior, and exterior angles. Finally, you can use angles like interior angles in construction or while building a F1 car you could use angles to make it more airodinamic.
100
How could you find the sum of the exterior angles?
The sum of exterior angles can be found by adding all the exterior angles but for polygons you will always get 360 degrees.
200
What are interior/ exterior angles?
Interior angles are angles on the inside of a shape and exterior angles are on the outside.
200
How could you catagorize two squares and a regular rectangle?
You can put them in a group that has only right angles.
200
What is a polygon?
A polygon is a shape that has no open areas, no intersecting lines, and no curved lines.
200
How do you measure angles?
You can measure angles using a protractor, an angle ruler, and even estimation.

#5 would be 45 degrees and #3 would be 135 degrees.
300
What are irregular/regular polygons?
Irregular polygons are polygons that have uneven angles and regular polygons have equal angles.
300
How could you compare concave and convex polygons?
One way to compare these is that they can have the same ammount of sides and angles.
300
What is a degree?
A degree is unit for measurement used in angles.
300
How could you determine the interior angle sum of a polygon?
You could use this formula: (n-2)x180=s n=number of sides s=angle sum
400
What are supplimentary/ complimentary angles?
Complimentary angles are either two angles whose sum is 90 degrees and supplimentary angles are either two angles whose sum is 180 degrees.
400
What can you contrast between regular and irregular polygons.
Regular polygons have every side the same length and every angle have to be the same, while irregular polygons can have any side length or angle length.
400
What are vertical angles?
Vaetical angles are each of the pairs of opposite angles made by two intersecting lines.
400
What is the measure of an interior angle in a regular rectangle?
The angle is: 90 degrees
500
What is a right angle?
A right angle is an angle that is 90 degrees.
500
How can you contrast polygons and non-polygons?
Polygons and non-polygons are different because for a polygon you have to have straight lines, no intersecting lines, and it has to be closed, but for a non-polygon you can make an hourglass, or a circle, or an open hourglass with a rounded bottom.
500
What is a transversal line?
A transversal line is a line that passes through two parallel lines.
500
How could you find the exterior angle in a regular polygon?
One way is you could find the supplimentary angle of one of the interior angles, or you can use this equation: 360÷n n=number of sides
