A straight line is divided into 2 angles one is 112 degrees. What is the other one?
What is 68 degrees.
100
Draw an equilateral triangle. How many degrees in each angle?
What is 60. All sides are equal.
100
Draw a parallelogram.
What is picture must have 2 sets of parallel lines.
100
What is the angle sum of a quadrilateral?
What is 360 degrees
100
Draw 2 parallel lines with a transversal. Put a star on all the angles that are the same. Put a dot on all the other angles that are the same.
What is (see picture).
200
A triangle has 2 angles that are 34 degrees and 62 degrees. How many degrees is the 3rd angle?
What is 84 degrees.
200
Draw an isosceles triangle What makes an isosceles triangle?
What is it has 2 sides that are the same length and one side that is different.
200
Draw a trapezoid that is not a parallelogram.
What is picture that has 4 sides, there is at least one set of parallel lines.
200
What is the angle sum of a pentagon?
What is 540 degrees.
200
See white board. How many degrees in angle B?
What is 88 degrees.
300
A triangle has an angle that is 17 degrees and an angle that is 23 degrees. How many degrees is the third angle.
What is 140 degrees.
300
Can I make a triangle with sides that are 4 units 5 units and 10 units? WHy or why not?
No, because 4 + 5 is less than 10.
300
I have geo strips with side lengths 3,3, 5, and 6. Can i make a quadrilateral? Why or why not?
What is yes. because the length of 3 sides is greater than the 4th.
300
What is the angle sum of a nonagon?
What is 1260 degrees.
300
a square has an exterior angle. How many degrees in the exterior angle?
What is 90 degrees.
400
A quadrilateral has two opposite angles that are 47 degrees. The third angle is 133 degrees. How big is the fourth angle. What kind of quadrilateral is this?
What is 133 degrees. This is a parallelogram, which is a type of trapezoid.
400
I have 3 geostrips. One is 8 units, one is 4 units and one is 11 units. Will this make a triangle? Why or why not?
What is yes, because the 2 smallest sides added up is greater than the third side.
400
I have geostrips that are 5 units 6 units 7 units and 20 units. Can i make a quadrilateral?
What is no, because 20 is larger than the other 3 sides added up.
400
What is the sum of one interior angle on a regular decagon?
What is 144 degrees.
400
An regular octagon has 8 exterior angles. How big is one of these exterior angles.
What is 45 degrees. 8-2 =6 6 x 180= 1080 degees total interior 1080 divided by 8 is 135 degrees. 180-135= 45 degrees.
500
A quadrilateral has 3 angles that are 50 degrees each. How big is the fourth angle. Sketch this quadrilateral.
What is 210 degrees. Has a concave angle like a boomerang.
500
I have 3 geostrips. One is 9 units long, one if 7 units long and one is 16 units long. Can these make a triangle? Why or why not?
What is no, two sides added up need to be greater than the third side, or it will not make a triangle. In this case, these would just make a straight line.
500
If I have side lengths that are 10, 12, 13, and 35, can I make a quadrilateral?
What is no, because the 4th side length needs to be greater than the 3 added up. Not equal.
500
How many degrees are in 1 interior angle of a regular octagon?
What is 135 degrees. The total degrees would be 8-2= 6. then 6 x 180 = 1080. Then, I divided 1080 by 8 (the number of angles) to get 135 degrees.
500
a shape has an interior angle of 77 degrees. what is the exterior angle?
What is 103 degrees. 180-77= 103
